Web10.53. Artinian rings. 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. WebFeb 1, 1976 · INTRODUCTION An approximately finite-dimensional C'*-algebra, briefly called an AF algebra, is a C'*-algebra that is the inductive limit of an increasing sequence of finite-dimensional C*-algebras, all with the same unit [1]. These algebras provide an interesting class of C*-algebras without Hausdorff separation of the primitive ideal spectrum.

WebThe point spectrum is often defined as the set of all isolated eigenvalues with finite multiplicity, i.e., as the set of those λ for which T (λ) is Fredholm with index zero, the null space of T (λ) is nontrivial, and is invertible for all in a small neighbourhood of λ (except, of course, for ). The sets Σ pt and differ in the following way.
