Some studies on dark energy related problems
In this work we perform some studies related to dark energy. Firstly, we propose a dynamical approach to explain the dark energy content of the universe. We assume that a massless scalar field couples to the Hubble parameter with some Planck-mass suppressed interactions. This scalar field developes a Hubble parameter-dependent (thus time-dependent) vacum expectation value, which renders a time-...
متن کاملglobal 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 کاملConsequences on some dark energy-candidates from SN 1997ff
We examine the status of various dark energy-models in light of the recently observed SN 1997ff at z ≈ 1.7. The modified data still fit a pure cosmological constant Λ or a quintessence with an equation of state similar to that of Λ. The kinematical Λ-models, Λ ∼ S and Λ ∼ H, also fit the data reasonably well and require less dark energy density (hence more matter energy density) than is require...
