Detection Theorem for Finite Group Schemes
The classical detection theorem for finite groups (due to D. Quillen [Q] and B. Venkov [Q-V]) tells that if π is a finite group and Λ is a Z/p[π]-algebra then a cohomology class z ∈ H(π,Λ) is nilpotent iff for every elementary abelian psubgroup i : π0 →֒ π the restriction i (z) ∈ H(π0,Λ) of z to π0 is nilpotent. This theorem is very useful for the identification of the support variety of the gro...

متن کاملNonstandard finite difference schemes for differential equations
In this paper, the reorganization of the denominator of the discrete derivative and nonlocal approximation of nonlinear terms are used in the design of nonstandard finite difference schemes (NSFDs). Numerical examples confirming then efficiency of schemes, for some differential equations are provided. In order to illustrate the accuracy of the new NSFDs, the numerical results are compared with ...
متن کاملInvariants of finite group schemes
Let k be an algebraically closed field, G a finite group scheme over k operating on a scheme X over k. Under assumption that X can be covered by G-invariant affine open subsets the classical results in [3] and [14] describe the quotient X/G. In case of a free action X is known to be a principal homogeneous G-space over X/G. Furthermore, the category of G-linearized quasi-coherent sheaves of OX ...
متن کاملThe Chevalley-shephard-todd Theorem for Finite Linearly Reductive Group Schemes
We generalize the classical Chevalley-Shephard-Todd theorem to the case of finite linearly reductive group schemes. As an application, we prove that every scheme X which is étale locally the quotient of a smooth scheme by a finite linearly reductive group scheme is the coarse space of a smooth tame Artin stack (as defined by Abramovich, Olsson, and Vistoli) whose stacky structure is supported o...
