大型通用变形环

Large universal deformation rings

Frauke M. Bleher

摘要:

我们给出了一系列有限群G和G的mod p表示V的例子,它们的稳定自同态都是由标量给出的,使得V有一个泛变形环R(G,V),在R(G,V)/pR(G,V)同构于一个单变量的幂级数代数的意义下,这个环是大的.

英文摘要:

We provide a series of examples of finite groups G and mod p representations V of G whose stable endomorphisms are all given by scalars such that V has a universal deformation ring R(G,V) which is large in the sense that R(G,V)/pR(G,V) is isomorphic to a power series algebra in one variable.
