global results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Estimating probabilities for unbounded categorization problems
We propose two output activation functions for estimating probability distributions over an unbounded number of categories with a recurrent neural network, and derive the statistical assumptions which they embody. Both these methods perform better than the standard approach to such problems, when applied to probabilistic parsing of natural language with Simple Synchrony Networks.
متن کاملProblems in Unbounded Cylindrical Domains
We combine the classical point of view of special functions with functional calculus for sectorial operators to obtain semi-explicit representation formulæ for the solutions.The formulæ are well suited for the further study of their properties as well as for the precise characterization of asymptotic behaviour in the large or for vanishing parameters (such as in perturbation theory). The approa...
متن کاملElliptic and parabolic problems in unbounded domains
We consider elliptic and parabolic problems in unbounded domains. We give general existence and regularity results in Besov spaces and semi-explicit representation formulas via operatorvalued fundamental solutions which turn out to be a powerful tool to derive a series of qualitative results about the solutions. We give a sample of possible applications including asymptotic behavior in the larg...
متن کاملUnbounded Extensions and Operator Moment Problems
Extension results, expressed in terms of complete boundedness, leading to necessary and sufficient conditions for the solvability of power moment problems with unbounded operator data are given. As an application, necessary and sufficient conditions for the existence of selfadjoint and normal extensions for some classes of commuting tuples of unbounded linear operators are obtained.
