Modular Invariant D - Modules
We studyD-modules over the modular curve of level 1 defined as an orbifold, and show that if such D-modules are of rank 1, these monodromy representations map the S-action to the identity. This means that in the orbifold case, there are linear representations of the fundamental groups which do not come from D-modules.
متن کاملTori Invariant under an Involutorial Automorphism I
Let G be a connected reductive linear algebraic group defined over an field k of characteristic not 2, θ ∈ Aut(G) an involutional k-automorphism of G and K = Gθ = {g ∈ G | θ(g) = g} the set of fixed points of θ. Denote the set of k-rational points of G by Gk. In this paper we shall classify the K-conjugacy classes of θ-stable maximal tori of G. This is shown to be independent of the characteris...
متن کاملTori Invariant under an Involutorial Automorphism Ii
The geometry of the orbits of a minimal parabolic k-subgroup acting on a symmetric k-variety is essential in several area’s, but its main importance is in the study of the representations associated with these symmetric k-varieties (see for example [6], [5], [20] and [31]). Up to an action of the restricted Weyl group of G, these orbits can be characterized by the Hk-conjugacy classes of maxima...
متن کاملEnsuring Invariant Contracts for Modules in Java
Deductive verification of object-oriented programs suffers from the lack of modularity. One of the obstacles to modular verification are invariant contracts, which classes extending a verified system could break. We introduce a concept of modules for Java and their correctness w.r.t. invariant contracts and give a theoretical criterion on attributes called module-protection. To ensure modular f...
متن کاملOplus-supplemented modules with respect to images of a fully invariant submodule
Lifting modules and their various generalizations as some main concepts in module theory have been studied and investigated extensively in recent decades. Some authors tried to present some homological aspects of lifting modules and -supplemented modules. In this work, we shall present a homological approach to -supplemented modules via fully invariant submodules. Lifting modules and H-suppleme...
