SOME RESULTS OF CONTINUITY ?f
The dynamical behavior of a map on the unit interval has been the subject of much contemporary research. In this paper, we will consider the relation between the continuity of the map cof and cof for some positive integer k, where f is a continuous map from the unit interval to itself, and ?f is a function which takes any element of the unit interval to the set of all subsequential limits o...
متن کاملSeparate and Joint Continuity of Homomorphisms Defined on Topological Groups
In this paper we prove the following theorem. “Let H be a countably Čech–complete topological group, X be a topological space and (G, ·, τ) be a topological group. If f : H ×X → G is a separately continuous mapping with the property that for each x ∈ X, the mapping h 7→ f(h, x) is a group homomorphism, then for each q–point x0 ∈ X the mapping f is jointly continuous at each point of H ×{x0}.” W...

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...

متن کاملSome Technical Results on Continuity , Strategy - proofness , and Related Strategic
There are many concepts of nonmanipulability, including strategy-proofness (and its several coalitional variants), Nash implementability, self Nash implementability, and nonbossi-ness. We explore the relationships between these concepts in the context of continuous social choice functions (SCF's). For any continuous SCF on a continuously and monotonically closed domain, we nd that strategy-proo...
