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...

Quantum iterative algorithm for image reconstruction problems

Iterative algorithm based on quantum tunneling is proposed by making use of meaneld approximation. W e apply our method to the problem of BW image reconstruction (IR). Its performance is in vestigated both analytically and numerically.

Some Exact Results for Quantum Lattice Problems

Physics is increasingly moving towards nano-scale technology, and with this comes the need to understand small lattices or quasi-lattices supporting a small number of quanta. Often this gives the quantum equivalent of a classical breather, though with some interesting differences. In this short paper we review some work on quantum lattice problems, concentrating mainly on the quantum discrete n...

Edge reconstruction in fractional quantum Hall states

The nature of edge reconstruction in the quantumHall e ect (QHE) and the issue of where the current flows have been debated for years.Moreover, the recent observation of proliferation of ‘upstream’ neutral modes in the fractional QHE has raised doubts about the present models of edge channels. Here, we present a new picture of the edge reconstruction in two of the holeconjugate states. For exam...

Quantum Complexity: Some Recent Results, Some Open Problems, Some Thoughts

This talk will discuss some recent results on the complexity theory of quantum computing. The long term goal is to understand exactly the relationship between the new quantum complexity classes and the classic ones. It is assumed that you are not an expert in: quantum flavordynamics, quantum geometrodynamics, quantum hydrodynamics, quantum magnetodynamics, quantum triviality, Schrödinger’s equa...
