In this paper, we attempt to introduce mainly the solvability of several boundary value problems for partial differential equations by using function theoretic methods. We first give the proper formulations of some elliptic boundary value problems and solution's stability, and then investigate various boundary value problems for several complex variables and in Clifford analysis. Meanwhile, we examine some parabolic equations and systems of hyperbolic equations as well as composite type equations. By applying the results of discontinuous boundary value problems for elliptic systems of first order, we solve the free boundary problems occuring such as in filtrations, gas dynamics and elastico-plastic mechanics. Furthermore, by using the finite element method and the Newton imbedding method in numerical analysis, we obtain the approximate solutions of some elliptic boundary value problems and quasiconformal mappings. Throughout this paper, in handling partial differential equations, we can see the advantage of function theoretic methodsi however, there remain many questions not yet solved.
