Interaction of nonlinear waves governed by Boussinesq equation
(Elsevier Ltd, 200612)In the present work, the nonlinear interactions of two acoustical waves governed by the Boussinesq equation with different wave numbers, frequencies and the group velocities are examined. For that purpose, we used the ...

An inverse source problem connected with thermoacoustic imaging in multilayer planar medium

An investigation of the certain class of multivalent harmonic mappings
(Eudoxus Press, 201603)The main purpose of the present paper is to investigate some properties of the certain class of sensepreserving pvalent harmonic mappings in the open unit disc D = {z is an element of C parallel to z vertical bar < 1}. 
Lagrangian dynamics on matched pairs
(Elsevier B.V., 201701)Given a matched pair of Lie groups, we show that the tangent bundle of the matched pair group is isomorphic to the matched pair of the tangent groups. We thus obtain the Euler–Lagrange equations on the trivialized matched ... 
Largest Eigenvalues of The Discrete PLaplacian of Trees with Degree
