#### Biography:

Mahammad A. Nurmammadov graduated from Mathematics and 1987 at Novosibirsk State University Post graduated with Ph. Degree of Physical Mathematics (dissertation title: On the solvability of a some boundary value problems for mixed type differential equations with some degenerating planes) Second degree Doctor of Science Researches (dissertation title: On the solvability of local and nonlocal boundary value problems for non-classical equations of mathematical physics in multi-dimensional domain) Worked in Novosibirsk State University (USSR), Head of department, and Vice-Rector of Scientific Affairs of Lankaran State University, associated professor at the Oil Academy Azerbaijan (department of applied mathematics ) and present Azerbaijan State Pedagogical University. He is Chief-in Editor of some of journals in America, member of editorial board of more than 17 journals of countries (America, Europe and so on), Member Scientific Committee. Organization Committee Reviewers of 43 International Conferences , Symposiums, more than 800 refereed papers, Published book in USA, and 47 papers and at the first time obtained New Typeless System Equations ( for linear and nonlinear cases ) and New Well-Posed Boundary Problems which is has application in physical fields, to the problems of transonic flow, noise, plasma. Moreover, obtained solvability of new boundary value problems for higher order non-classical linear equations.
