The first integral method (FIM) is extended to find the explicit exact solutions of high-dimensional nonlinear partial differential equations (PDEs). The considered models are: the space-time modified regularized long wave (mRLW) equation, the (1+2) dimensional space-time potential Kadomtsev Petviashvili (pKP) equation and the (1+2) dimensional space-time coupled dispersive long wave (DLW) system. FIM is a powerful mathematical tool that can be used to obtain the exact solutions of many non-linear PDEs.<\/jats:p>","DOI":"10.3390\/sym11060783","type":"journal-article","created":{"date-parts":[[2019,6,12]],"date-time":"2019-06-12T10:55:19Z","timestamp":1560336919000},"page":"783","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["First Integral Technique for Finding Exact Solutions of Higher Dimensional Mathematical Physics Models"],"prefix":"10.3390","volume":"11","author":[{"given":"Shumaila","family":"Javeed","sequence":"first","affiliation":[{"name":"Department of Mathematics, COMSATS University Islambad, Islamabad Campus, Park Road, Chak Shahzad Islamabad 45550, Pakistan"}]},{"given":"Sidra","family":"Riaz","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Riphah International University, Sector I-14, l Islamabad 45240, Pakistan"}]},{"given":"Khurram","family":"Saleem Alimgeer","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, COMSATS University Islambad, Islamabad Campus, Park Road, Chak Shahzad Islamabad 45550, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7356-4275","authenticated-orcid":false,"given":"M.","family":"Atif","sequence":"additional","affiliation":[{"name":"Department of Physics and Astronomy, College of Science, King Saud University, Riyadh 11451, Saudi Arabia"}]},{"given":"Atif","family":"Hanif","sequence":"additional","affiliation":[{"name":"Botany and Microbiology Department, College of Science, King Saud University, Riyadh 11451, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0286-7244","authenticated-orcid":false,"given":"Dumitru","family":"Baleanu","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Cankaya University, Ankara, Turkey and Institute of Space Sciences, 06530 Magurele-Bucharest, Romania"}]}],"member":"1968","published-online":{"date-parts":[[2019,6,12]]},"reference":[{"key":"ref_1","unstructured":"Kilbas, A.A.A., Srivastava, H.M., and Trujillo, J.J.
