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 کاملThe unit sum number of discrete modules
In this paper, we show that every element of a discrete module is a sum of two units if and only if its endomorphism ring has no factor ring isomorphic to $Z_{2}$. We also characterize unit sum number equal to two for the endomorphism ring of quasi-discrete modules with finite exchange property.
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 کاملComplex Maps without Invariant
We consider complex polynomials f (z) = z ℓ + c1 for ℓ ∈ 2N and c1 ∈ R, and find some combinatorial types and values of ℓ such that there is no invariant probability measure equivalent to conformal measure on the Julia set. This holds for particular Fibonacci-like and Feigenbaum combinatorial types when ℓ sufficiently large and also for a class of 'long–branched' maps of any critical order.
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...
