Geometric aspects of rings and representations theories

چکیده
Lors de la quantification algébrique d'une algèbre de Pois-son, il est intéressant que certains groupes de (co)homologie suivent cette déformation de Poisson en Hochschild. Nous présenterons ce thème relative-ment au groupe des traces en donnant des exemples provenant de variétés quotients par l'action de groupes finis, typiquement pour les singularités de Klein, les actions doublées de groupes de Weyl et certaines actions multi-plicatives.

Classification and properties of acyclic discrete phase-type distributions based on geometric and shifted geometric distributions
Acyclic phase-type distributions form a versatile model, serving as approximations to many probability distributions in various circumstances. They exhibit special properties and characteristics that usually make their applications attractive. Compared to acyclic continuous phase-type (ACPH) distributions, acyclic discrete phase-type (ADPH) distributions and their subclasses (ADPH family) have ...
متن کاملOmega-almost Boolean rings
In this paper the concept of an $Omega$- Almost Boolean ring is introduced and illistrated how a sheaf of algebras can be constructed from an $Omega$- Almost Boolean ring over a locally Boolean space.
متن کاملChiral Rings and Phases of Supersymmetric Gauge Theories
We solve for the expectation values of chiral operators in supersymmetric U(N) gauge theories with matter in the adjoint, fundamental and anti-fundamental representations. A simple geometric picture emerges involving a description by a meromorphic one-form on a Riemann surface. The equations of motion are equivalent to a condition on the integrality of periods of this form. The solution indicat...
متن کاملPragmatic Representations in Iranian High School English Textbooks
Owing to the growing interest in communicative, cultural and pragmatic aspects of second language learning in recent years, the present study tried to investigate representations of pragmatic aspects of English as a foreign language in Iranian high school textbooks. Using Halliday’s (1978), and Searle’s (1976) models, different language functions and speech acts were specifically determined and...
متن کاملGeometric Engineering of Quantum Field Theories
Using the recent advances in our understanding of non-perturbative aspects of type II strings we show how non-trivial exact results for N = 2 quantum field theories can be reduced to T-dualities of string theory. This is done by constructing a local geometric realization of quantum field theories together with a local application of mirror symmetry. This construction is not based on any duality...
