We consider three classes of nonlocal diffusion operators that are not necessarily symmetric,and characterize their principal eigenvalues in a uniform,min-max fashion.
There has been substantial effort to develop ab initio electronic structure calculations that use localized basis functions for much fewer degrees of freedom.
In this talk,we firstly present a regularized optimization method without iteration for some inverse problems of linear diffusion equation,such as inverse source problem of parabolic equation,the inve
One of the most efficient way of solving multidimensional ill-posed problems is using of parallel computing that helps us to process a huge amount of data.
