فرض کنیم (r,m) یک حلقه ی گورنشنتاین n بعدی است، برای یک ایده آل i?r با ارتفاع c ، حلقه ی درون ریختی b=?hom?_r (h_i^c (r),h_i^c (r) ) را مورد بررسی قرار می دهیم. می توان نشان داد که b یک حلقه ی جابجایی است. در حالتی که (r,m) یک حلقه ی موضعی منظم شامل یک میدان باشد، b یک حلقه ی کوهن مکولی است. ویژگی های این حلقه وابسته به بزرگترین عدد لیوبزنیک l=?dim?_k ?ext?_r^d (k,h_i^c (r) ) است که d=dim??r?i?...

Abstract The aim of this article is to provoke discussion concerning arithmetic properties the function $p_{d}(n)$ counting partitions a positive integer n into d th powers, where $d\geq 2$ . Apart from results asymptotic behaviour , little known. In first part paper, we prove certain congruences involving functions various types powers. second paper experimental and contains questions conjectu...

+146% 0 –35% European research got a mixed report card in an analysis released last week by the European Union. The report says that the 27 E.U. nations have done well at increasing their research work force: Numbers grew twice as fast as in the United States between 2000 and 2006, reaching 640,000 researchers, while also attracting more foreign researchers to come and work there. Europe also a...

BACKGROUND AND PURPOSE Stroke is frequently associated with autonomic dysfunction, which causes secondary cardiovascular complications. Early diagnosis of autonomic imbalance prevents complications, but it is only available at specialized centers. Widely available surrogate markers are needed. This study tested whether stroke severity, as assessed by National Institutes of Health Stroke Scale (...

Recently, in Quantum Field theory, there has been an interest in scattering in highly singular potentials. Here, solutions to the stationary Schrödinger equation are presented when the potential is a multiple of an arbitrary positive power of the Dirac delta distribution. The one dimensional, and spherically symmetric three dimensional cases are dealt with. 1. One space dimension In Rosinger [4...

One of the major questions in the theory of Toeplitz operators on the Bergman space over the unit disk D in the complex plane C is a complete description of the commutant of a given Toeplitz operator, that is the set of all Toeplitz operators that commute with it. In [4], the first author obtained a complete description of the commutant of Toeplitz operator T with any quasihomogeneous symbol φ(...

We prove some suffcient conditions in order that a root of the Bernstein–Sato polynomial contributes to difference between certain $D$-modules generated by rational powers holomorphic function; for instance, this holds case isolated singularities with semisimple Milnor monodromies. then construct an example where does not contribute difference. This also solves old open problem about relation m...
