Some Problems on the 'Sen-soku'

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...

On Sen and Aristotle

In this paper I maintain that Amartya Sen’s Capability Approach (CA) implies a recuperation of practical science in Economics. Sen’s proposal has some problems closely related to this practical character: the heterogeneity and incommensurability of capabilities, its ambiguity concerning the use of the term “capability”, and the consequent lack of operative character of the CA. Sen recognizes th...

Construing Sen on Commitment

One of Amartya Sen’s most distinctive claims, and perhaps also one of his most controversial, is that there is an altruistic attitude toward others that does not make sense within the terms of rational choice theory, however broadly that theory is construed. He describes this attitude as one of “commitment” to others, contrasting itwith egoismandalsowith adistinct altruistic attitude he calls “...

On some factorization problems

We consider three notions of factorization arising in different frameworks: factorizing languages, factorization of the natural numbers, factorizing codes. A language X ⊆ A∗ is called factorizing if there exists a language Y ⊆ A∗ such that XY = A∗ and the product is unambiguous. This is a decidable property for recognizable languages X . If we consider the particular case of unary alphabets, we...
