Rakhim Aitbayev

Many phenomena in sciences and engineering are described by partial differential equations (pd). Exact solutions of most of real world 问题 are often very difficult or 不可能获得. 这类问题的解可以用数值方法近似求得 方法. Numerical Methods for Solving PDEs is a vast area which deals with numerical errors, computational stability, parallel algorithms, efficient computation, and solution 挑战多物理场问题. 我的研究兴趣如下 areas of Numerical PDEs: orthogonal spline collocation method, iterative 方法 for solving large sparse systems of equations, numerical solution of nonlinear elliptic PDEs, numerical solution of non-self-adjoint or indefinite 问题, and interface 问题.
