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 some problems related to palindrome closure
In this paper we solve some open problems related to (pseudo)palindrome closure operators and to the infinite words generated by their iteration, that is, standard episturmian and pseudostandard words. We show that if θ is an involutory antimorphism of A, then both θ-palindromic closures of any factor of a θ-standard word are also factors of some θ-standard word. We also introduce the class of ...
متن کاملSome problems related to bisimilarity on BPP
Jančar has in 2003 shown that bisimilarity on Basic Parallel Processes (BPP) can be decided in polynomial space. Bisimilarity is studied on various subclasses of BPP as well. We present summary of known complexity bounds of some such bisimilarity problems. Moreover is here shown that deciding regularity of a BPP is PSPACE-complete. So far this problem was only known to be PSPACE-hard.
متن کاملSome Decision Problems Related To
The problem of deciding whether a monoid that is given through a nite presentation is a regular monoid as well as two closely related decision problems are considered. Since these problems are undecidable in general, they are investigated for certain restricted classes of nite presentations. Some new decidability results as well as some new undecidability results are obtained, which show that f...
متن کاملBiochemical Approaches to Wood Preservation
Much progress has been made in the past several years concerning the biochemistry and molecular genetics of fungal wood decay. Aspects of this knowledge were obtained with the intent of using the fungi and their enzymes for selective and beneficial purposes; e.g., in biopulping and biobleaching of wood fiber, in bioremediation of pollutants, and in biomass conversions for fuel and chemical feed...
