Isotypical representation

In group theory, an isotypical, primary or factor representation of a group G is a unitary representation such that any two subrepresentations have equivalent sub-subrepresentations. This is related to the notion of a primary or of a C*-algebra, or to the factor for a von Neumann algebra: the representation of G is isotypical iff is a factor. This term more generally used in the context of semisimple modules. (Wikipedia).

Isomorphism

What does it mean for two spaces to be isomorphic? In this video, I define the notion of isomorphism of vector spaces, and show that P2 and R3 are isomorphic. Dimension and Isomorphism (sequel): https://www.youtube.com/watch?v=EjiLTke3j7o Check out my Linear Transformations Playlist: ht

23 Algebraic system isomorphism

Isomorphic algebraic systems are systems in which there is a mapping from one to the other that is a one-to-one correspondence, with all relations and operations preserved in the correspondence.

Isomorphisms in abstract algebra

In this video I take a look at an example of a homomorphism that is both onto and one-to-one, i.e both surjective and injection, which makes it a bijection. Such a homomorphism is termed an isomorphism. Through the example, I review the construction of Cayley's tables for integers mod 4

Iva Halacheva: The cactus group, crystals, and perverse equivalences

Suppose C is a category equipped with a categorical action of a (simply-laced) semisimple Lie algebra g. Chuang and Rouquier construct equivalences on its derived category $D^b(C)$ via the so called Rickard complexes, one for each simple root of g. These complexes satisfy the braid relatio

In this lecture series, we will focus on the recent advance on the Beilinson-Bloch conjecture for unitary Shimura varieties, more precisely, a Gross-Zagier type formula for automorphic forms on unitary groups of higher ranks. We will start from the general theory of height pairings between

What are Isomorphic Graphs? | Graph Isomorphism, Graph Theory

How do we formally describe two graphs "having the same structure"? The term for this is "isomorphic". Two graphs that have the same structure are called isomorphic, and we'll define exactly what that means with examples in today's video graph theory lesson! Check out the full Graph Theor
