The spectrum of a finite dimensional algebra
WebThe usefulness of the notion of spectrum of an operator on a Hilbert space is the analogy to eigenvalues of operators on nite-dimensional spaces. Naturally, things become more complicated in in nite-dimensional vector spaces. 1. Generalities on spectra It is convenient to know that spectra of continuous operators are non-empty, compact subsets ... WebOct 29, 2024 · The spectrum of a linear operator on a finite-dimensional space over an arbitrary field is the set of its eigen values. The problem of classifying endomorphisms of finite-dimensional spaces over an algebraically closed field has been completely solved, and the similarity classes have been described in terms of the invariant subspaces.

Finite-dimensional linear algebra suggests that two linear maps T 1, T 2: H 1!H 2 which are linked by a formula (1.1) T 2 U 1 = U 2 T 1; for some invertible operators U i: H i!H i, share many similar properties. In the nite-dimensional case, this is because the U i correspond to ...

Artinian rings, and especially local Artinian rings, play an important role in algebraic geometry, for example in deformation theory. Definition 10.53.1. A ring R is Artinian if it satisfies the descending chain condition for ideals. Lemma 10.53.2. Suppose R is a finite dimensional algebra over a field. Then R is Artinian.
