In abstract algebra, a representation of an associative algebra is a module for that algebra. Here an associative algebra is a (not necessarily unital) ring. If the algebra is not unital, it may be made so in a standard way (see the adjoint functors page); there is no essential difference between modules for the resulting … See more Linear complex structure One of the simplest non-trivial examples is a linear complex structure, which is a representation of the complex numbers C, thought of as an associative algebra over the See more Eigenvalues and eigenvectors can be generalized to algebra representations. The generalization of an eigenvalue of an algebra representation is, rather than a single scalar, a one … See more • Representation theory • Intertwiner • Representation theory of Hopf algebras See more WebMar 15, 2024 · The algebra $ A $ is said to be representation-finite if there are only finitely many isomorphism classes of indecomposable representations of $ A $; it is called …

WebNov 2, 2015 · 2. I have to do this exercise: Given an abelian Lie algebra h on an algebraically closed field F. Let φ: h → End F ( V) be a representation over the finite dimensional vector space V over F. For every λ ∈ h ∗ = Hom F ( h, F) define. V λ = { v ∈ V φ ( h) v = λ ( h) v, ∀ h ∈ h } Prove that V = ⨁ λ ∈ h ∗ V λ. Webalgebra is the algebra EndV of linear operators from a vector space V to itself. Other important examples include algebras defined by generators and relations, such as … marini gioia did
