Problems about nature ore mining type and nature mineralizing boundary have been discussed.

in this paper we have proved that certain random Taylor series almost surelyconverges with its convergence circle as the natural boundary, that is, this series cannot beanalytically extended out of its convergence circle.

Meshless method based on natural boundary element;

The coupling method of natural boundary element and finite element for KPZ equation in unbounded domains;

For the purpose of speeding up computing and reducing calculation amount,we propose a coupling method between natural boundary element and finite element for infinite plane elastic problem in ANSYS,describe the theoretical basis of the coupling method,and introduce the concrete steps in ANSYS.

The finite element method is combined with the natural boundary element method to study the weak solvability and Galerkin approximations of a class of semilinear exterior boundary value problems.

In this paper, we combine a finite element approach with the natural boundary element method to stduy the weak solvability and Galerkin approximations of a class of semilinear exterior boundary value problems.

In this paper,we investigate the natural boundary element method for the boundary value problem of Helmholtz equation in an exterior elliptic domain.

In this paper we discuss the natural boundary element method for harmonic equation in an exterior elliptic domain.

In this paper,we investigate the natural boundary element method for an anisotropic problem in an infinite domain with a concave angle.

Then the natural boundary reduction,suggested by Feng and Yu,is applied to deal with the three dimensional problems.

These algorithms are given by both the finite element A- method and the nonoverlapping domain decomposition method based on the natural boundary reduction.

Based on the theory of natural boundary reduction,non-overlapping domain decomposition method is applied to elliptic boundary value problems on a kind of unbounded half plane with a cave.
