Computational and mathematical approach for recent problems in mathematical sciences

This special issue on Computational and mathematical approach for recent problems in mathematical sciencesis the compilation of the short listed papers of 4th International Conference on Mathematical Techniques in Engineering Applications (ICMTEA2020) held during 4–5 December 2020 in Graphic Era (Deemed to be University), Dehradun, Uttarakhand, India. In this issue, we selected nine papers which have gone through several rounds of review and revision, and represent a cross-section of research in mathematical analysis and computational approach of solving complex mathematical problems occurs in engineering and sciences that touch upon both technical and managerial issues. The articles on mathematical analysis, computational approach, efficient algorithm for computation, solving nonlinear reaction-diffusion equation, effect of mass transfer and radiation on mixed convection boundary layer flow, solutions of (3þ 1)-burgers system, optimization using NSGA-II, numerical treatment for the comparative study of MHD flow of Nano liquids, and computational study of seismic wave propagation. The guest editors are grateful to contributors who have made remarkable contributions and present their papers in the ICMTEA2020 during COVID19 pandemic. The guest editors are also grateful to reviewers for their valuable comments and suggestions which helped in improving the quality of the papers. Guest editors are also highly thankful to Editor-in-Chief & Associate Editors for providing the continuous support and constructive suggestions during the review process and shaping the special issue. We hope that this special issue makes significant contributions in the field of recent advancement in mathematical and computational field. We acknowledge International Journal for Computational Methods in Engineering Science & Mechanics for their kind support and help in bringing out this special issue.
