Prof.T.Vashakmadze is a high level researcher in pure and applied mathematics but as my topic is solid mechanics. I’m considering his works in corresponding direction. These works not only present extensions of some corresponding achievements of the Georgian school of mathematicians created by N. Muskhelishvili and I. Vekua but they also present new perspective developments in the continuum mechanics.One of the most valuable mathematical contributions is related to the numerical solution of initial value problems for ODEs. His approach is based on the application of Gauss and Clenshaw-Curtis type quadratures and Hermite interpolation process. He has proved that the Adam’s type multistep finite-difference schemes converge as O(h2n) for any finite integer n and are absolutely stable if the matrices of nodes are normal in Fejer’s sense [Vashakmadze,2010].
Another outstanding result is related to construction of the stable projective methods using the linear form of classical orthogonal polynomials as coordinate systems and their numerical realizations for a design of 2D BVPs (in bounded and unbounded domains). These efficient and optimal (in some sense) methods increase the possibilities of classical finite-difference, exponential-fitted, variational-discrete and continuous analogue of alternating-direction methods.
