Scientific perspectivism

0:00 And this is going to involve a high-level survey of Vial's trajectory through his work on representation in sleep groups, while its re-representation theory of the classical group might be the right track to go down. Actually, this is a paper that Vial contributed to 970th birthday, Normal Activity, and they're given by the representation theory.

2:30 The symmetric group to linear representation of the whole business really occurs in the first chapter of his book on the classical group where he's talking about the quantity Q of A.

5:00 If you want some of the really detailed, I recommend you turn to Thomas Hawking's book on the theory of Z-groups where he actually explores the related components of Hawking's book. He does a lot of work on introducing group theory into quantum mechanics. We have been concerned largely with things like vial derivation of the ascending vial program, deriving basics, cross-processing, essentially more general, it's an overview of the trajectory of the vial, and how, in particular, vial use group representations answer a priori, and to show that with a governing epistemological methodology, which vial pulse constructs in science, and an a priori statement in physics of the possible linear covariant quantities.

10:00 In the world of language, attributes regarded as inherent to things are not given, but recognized through their invariance when combined with other elements or variations. Symbolic constructs create an association with what is given and lead to it. So these attributes are projected on the background of the possibilities created by tree construction. And this is something that Weil, this characterization of constructive cognition, is found quite widely in Weil. There are all kinds of mental ideologies. But here are two which give you the flavor of the impossibility of physical reality other than on the fact that it comes into consciousness as a general form of consciousness, as an inner penetration of being and essence, of this. And Sunni aliancy is also very comparable. He doesn't actually cite this fact. He's laying out a kind of metaphysical phase model there as before. And he says the inner understanding of this inner penetration is, I think, just more of a vital version of transcendental necessity. That was the realist's report.

12:30 The non-file B or the actual is projected onto the background of the possibilities, which is involved by iterating the same step again and again, and a priori surveying the range of variability. We try to think of this as the actual projected as far as the symmetry of that statement on the background of the possibilities, as a group theoretic. This projection on the background of the possibilities is the method of mathematics for vials, and here again we design a theoretical picture of what is against the background of the possible. We talked about the point of intersection of the branch of freedom, the essence of man, and in physics, theoretical physics, in physics we apply some of the possible actual competitors on the Bayes method in general. It turns out that George Mackey was a student at RISE.

15:00 G, associating with each element of G, a linear transformation in an n-dimensional vector state B over a field of numbers of k, a real complex quaternion. The abstract group G is linear group and you've got two linear representations. Representation is reducible if there is in D a non-zero invariant proper subspace as an invariant complement. The decomposition of the representation space, D, is helpful to know that finding the irreducible given a representation can ask what irreducible contains and what multiplicity.

17:30 I think that the language of invariance belongs to the abstract of G, and the language of covariance belongs to the representation of the co-variance. Sure, sure, obviously. Obviously what I'm talking here about should probably more correctly be covariance. Vial is principally concerned with tensor quantities, receipts, and linear quantities, and then by employing tensors as models or representation models for irreducible, essentially clarifies the interdependence of linear quantities.

20:00 And now we've got the relativity problem as the problem of decomposition and tensor representation, finding the transformations of all kinds of possible ranks over the underdub relative to mass transfer. I'm not going to go into permanence in the representation group, but it's a big deal for Weil because it's helping to see that the possible symmetry characteristics of tensors are given rank, given by the representation theory. Tensors within each symmetry class can be added as they compose. In the paper that I mentioned earlier, where he discovered the connection between symmetry classes of tensors and irreducible representation. In addition, A can be keyed to a sum of simple tensor types, characterized by irreducibility and characteristic. And here, for him, the unimodular group. But as we know, irreducibly invariant times the tens of a given rank can provide a symmetric type. There are both symmetric and anti-symmetric tens of a given rank. Then spectral decomposition yields both symmetric and anti-symmetric. Now, with this complication, the problem becomes to decompose the tensor space as far as possible in subspaces invariant with respect to all symmetry transformations.

25:00 The appearance of spin is unavoidable as long as the wave quantity is high enough to be able to do it. I'm going to skip over a lot of stuff here, which will go outside the bounds of what I want to do in the talk, but basically what he does is to extend the representation theory of the wave equation, and it comes up with these two valued representations of special problems. And if you want to know further details, you can see the decomposition formula. The reduction of a representation is the reduction of the quantum quantities. There's still one outstanding problem, called the problem of symmetry in quantum mechanics, which is to answer the question, why are fermions willing to have the areas of multiple states? Yeah, well, the Leibniz-Hawley Exclusive Principle is actually later language that doesn't appear in the group theory in Karmann Hacks, but it appears in philosophy, mathematics, and mathematics. Naturally, we can assess the property laws between representations of finite metrics and finite systems, as well as the grid relations between their compounds and their characters.

27:30 I'll go over the main points quickly. I think I covered the main points. I'm going to go over what the main points are. An a priori statement in physics lies in formulating the general notion of covariant quantities. Here, again, looking at the treatment. A is a representation of an abstract group of gamma and coordinates of any multiple of numbers such as vectors and number fields such as k vectors. Then a quantity Q of type A is characterized by a representation A of gamma in k of a certain degree n. It is obviously of paramount importance to know whether a quantity breaks up into a number of independent primitive and partial quantities, i.e. whether a given representation A makes a two-permeable subset P1 of P invariant under the operation A of S of A possesses a complementary invariant subset P2 such that the whole representation state breaks up into the same part P1. The answer is true for any representation of A. Gamma, the answer is affirmative. The most important case is the finite group. That was just that result with that bridge formula, calculating root character.

30:00 Concluding, objectivity, here, I think, made that invariant quantity. But only in relation to an arbitrarily assumed form of a subsistence and adherent symbol, already gained by Leibniz. Quite remarkable, of course.

32:30 Not to my knowledge, what's so interesting about this work on the representation theory of the group is that it seems to have been done just as a transition from classical and it seems to be an approach that is general enough in many ways to apply to both. Because even the possibilities that you are going to see are going to be possibilities of so great quantity, so I agree with you on the situation.

35:00 I'm wondering about how this would be expressed in a modern way. What space are the tensors over here? We can also consider the space of all connections. For instance, in the community we call it the gate gate, this would be the configuration space. The connections, they are not web representations, which are not linear. Thank you for your attention.

37:30 Thank you for your attention. I'm not so sure that it's different. I use this as a later phrasing because it's more compact. Thank you for your attention.

40:00 Well, I mean, I, I, I don't see that in, in, in, in, in, in, in, in, in, in, in, in, in, in, in,
