Lie AlgebrasLet . be a Hopf algebra. We are going to study the .-lincar operators .: . → . which are translation-invariant. As in the previous part, we begin by seeing what this means when . is the ring of functions on an algebraic matrix group ..blithe 发表于 2025-3-25 13:34:05

My first goal thus has been to take three different viewpoints and demonstrate how they offer complementary intuitive insight into the subject. In Part I we begin with a functorial idea, discussing some familiar processes for constructing groups. ThOffensive 发表于 2025-3-25 20:34:49
Affine Group Schemespe; we can, for instance, get a group by taking all 2 ×2 matrices . over . satisfying . = .. A little less familiar isµ., the .th .: if we set µ.(.) = {. ∈ .|. = 1 }, we get a group under multiplication. All these are examples of affinc group schcmcs.支架 发表于 2025-3-26 04:02:38

Connected Components and Separable Algebras of connected components, we need a fancier version that will detect these “potential idempotents.” Over fields—and for the rest of this part we assume . is a field—the question can be handled using separable algebras.巧思 发表于 2025-3-26 19:44:52
