In this chapter we present these calculations for some particular but nevertheless important classes of nilpotent Lie algebras : i.e. the filiform algebras and the nilradicals of parabolic algebras. We restrict ourselves here to the cohomology whose coefficients are in the adjoint module; some ...
Let be a group scheme of finite type over a field, and consider the cohomology ring () with coefficients in the structure sheaf. We show that () is a free module of finite rank over its component of degree 0, and is the exterior algebra of its component of degree 1. When is connecte...

Let be a group of Möbius transformations and the space of complex polynomials of degree some fixed even integer. Using the action of on defined by Eichler, we compute the dimension of the cohomology space , first for an arbitrary -group (a generalization of Fuchsian group) and then for ...
and Lie algebras. Let k = F p be the field of p elements. By an algebra A we mean a non-negatively graded, associative k-algebra with product µ : A ⊗ A → A, unit η : k → A and augmentation ǫ : A → k. We assume A is locally finite, that is each A n ON...

It is known that the Betti numbers of the Heisenberg Lie algebras are unimodal over fields of characteristic two. This note observes that they are log-concave. An example is given of a nilpotent Lie algebra in characteristic two for which the Betti numbers are unimodal but not log-concave.年...
