A Cohomology Attached to a Function
In this paper, we study a certain cohomology attached to a smooth function, which arose naturally in Poisson geometry. We explain how this cohomology depends on the function, and we prove that it satisfies both the excision and the Mayer-Vietoris axioms. For a regular function we show that the cohomology is related to the de Rham cohomology. Finally, we use it to give a new proof of a well-know...
متن کاملGraded Prime Ideals Attached to a Group Graded Module
Let $G$ be a finitely generated abelian group and $M$ be a $G$-graded $A$-module. In general, $G$-associated prime ideals to $M$ may not exist. In this paper, we introduce the concept of $G$-attached prime ideals to $M$ as a generalization of $G$-associated prime ideals which gives a connection between certain $G$-prime ideals and $G$-graded modules over a (not necessarily $G$-graded Noetherian...
متن کاملTOP LOCAL COHOMOLOGY AND TOP FORMAL LOCAL COHOMOLOGY MODULES WITH SPECIFIED ATTACHED PRIMES
Let (R,m) be a Noetherian local ring, M be a finitely generated R-module of dimension n and a be an ideal of R. In this paper, generalizing the main results of Dibaei and Jafari [3] and Rezaei [8], we will show that if T is a subset of AsshR M, then there exists an ideal a of R such that AttR Hna (M)=T. As an application, we give some relationships between top local cohomology modules and top f...
متن کاملGalois Representations Attached to Tensor Products of Arithmetic Cohomology
We compute the action of Hecke operators on tensor products of cohomology classes of lower congruence subgroups of SL(n,Z) in trivial weight. We use this computation to prove that if each representation in a collection of Galois representations is attached to a cohomology class of a lower congruence subgroup in trivial weight, then a sum of certain twists of the representations consistent with ...
متن کاملAn Attached Odontoma to the Roots of a Mandibular Molar Tooth: A Case Report
Introduction: Odontomas are the most common odontogenic tumors. These lesions are usually considered a hamartoma than a neoplasm. Unlike normal tooth morphology, tissue arrangement is irregular in these lesions. Odontoma has self-limiting and slow growth, and if left untreated, its size will not increase over time. Most of these lesions are clinically asymptomatic and are detected on routine ra...
