Let f: X u2192 Y be a finite type morphism of locally noetherian schemes. It is well known ([3, IV, 7.8.6]) that the excellent property ascends from Y to X. On the other side there are counter-examples where X is excellent and Y is not. First of all it is easy to show that...
Y λ= SpecA λ Each B λ J is a finite generated A λ Algebra.If X → SpecR is finite, then X is said to be R-algebra. If k is an algebraically closed field and V is an integer, separable k-almost type of algebra over k, then we call V an algebraic variety over k....
Abelian groups, as well as finite groups and solvable groups are amenable. We now determine the homogenization of the quasi-morphisms gσ ∈ QM(F ) defined in the previous section. Lemma 3.5. Let x, y ∈ F . 7 (i) If x is a power then gσh(x) = 0, otherwise gσh(x) = ...
Ticket #13214 introduced the .is_identity() method. The implementation only treats parents with finite number of gens, but it assumes that the base has no non-trivial automorphisms. This gives unexpected results: sage: K.<z> = GF(4) sage...
Let Tilt(U_q({\mathfrak {g}}), {\mathbb {Q}}(q)) denote the category of tilting modules in the category of finite dimensional modules of Lusztig’s quantum group where {\mathfrak {g}} is a semisimple Lie algebra and q a primitive \ell -th root of unity where \ell > h and ...
is a k-algebra of finite type. It is the coordinate ring of the affine toric variety [Math Processing Error]. In addition, if the cone [Math Processing Error] is of dimension n, then there is a unique minimal system of generators [Math Processing Error] of the semigroup [Math Processing...
finite groups of Lie typealgebraic groupsindecomposable representationsmaximal subgroupsThe following problem is considered. Given a homomorphism :X鈫扜 between finite groups of Lie type in characteristic p, when can this be lifted to a morphism of suitable algebraic groups. In the special case where...
