For a Poisson manifold M we develop systematic methods to compute its Picard group Pic(M), i.e., its group of self Morita equivalences. We establish a precise relationship between Pic(M) and the group of gauge transformations up to Poisson diffeomorphisms showing, in particular, that their connected components of the identity coincide; this allows us to introduce the Picard Lie algebra of M and...

In this paper we contribute to the model theory of fuzzy logic in narrow sense The main topic is to demonstrate that analogues of the classical theorems characterizing the relation beween the form of axioms of a theory and the structure of the corresponding class of its models can be proved also in fuzzy logic Here we will prove theorem stating that every submodel of a model of a fuzzy theory i...

We consider an investment model where the objective is to overperform a given benchmark or index. We study this portfolio management problem for a long term horizon. This asymptotic criterion leads to a large deviation probability control problem. Its dual problem is an ergodic risk sensitive control problem on the optimal logarithmicmoment generating function that is explicitly derived.A caref...

We present several results on the compactness of space morphisms between analytic spaces in sense Berkovich. show that under certain conditions source, every sequence maps having an affinoid target has a subsequence converges pointwise to continuous map. also study class arise this way. Locally, they turn be after base change. Our naturally lead definition normal families. give some application...

Let G be a simple complex algebraic group equipped with a factorizable Poisson Lie structure. Let U~(g) be the corresponding quantum group. We study U~(g)-equivariant quantization C~[G] of the affine coordinate ring C[G] along the Semenov-Tian-Shansky Poisson Lie bracket. For a simply connected group G we prove an analog of the KostantRichardson theorem stating that C~[G] is a free module over ...

background:   iran places sixth amongst high risk natural disaster countries and guilan province of iran shoulders a large amount of socio-economic burden due to snow catastrophes. the more knowledge of circumstances we have, the more efficient our future encounters will be. methods: in this retrospective study, of all of the patients admitted to poursina hospital due to snow and ice related tr...

Recently, the world has been challenged with two major crisis; global climate change and rapid population growth. These impediments have led to hunger, poverty, socioeconomic crisis, political instability, increase disease burden and mortality rate. In an effort to circumvent these challenges, the united Nation in 2000 officially established in a summit the Millennium Development Goals (MDGs). ...

Reachability Logic is a recently introduced formalism, which is currently used for defining the operational semantics of programming languages and for stating properties about program executions. In this paper we show how Reachability Logic can be adapted for stating properties of transition systems described by Rewriting-Logic specifications. We propose an automatic procedure for verifying Rew...

Let G be a simple complex factorizable Poisson algebraic group. Let U (g) be the corresponding quantum group. We study the U (g)-equivariant quantization C [G] of the affine coordinate ring C[G] along the Semenov-Tian-Shansky bracket. For a simply connected group G, we give an elementary proof for the analog of the Kostant–Richardson theorem stating that C [G] is a free module over its center.
