University of Tabriz Computational Methods for Differential Equations 2345-3982 6 1 2018 01 01 Exact solutions of a linear fractional partial differential equation via characteristics method 12 18 6807 EN Elham Lashkarian Department of Mathematics, Shahrood University of Technology, Shahrood, Semnan, Iran Seyed Reza Hejazi Department of Mathematics, Shahrood University of Technology, Shahrood, Semnan, Iran Journal Article 2017 02 04 ‎In recent years‎, ‎many methods have been studied for solving differential equations of fractional order‎, ‎such as Lie group method, ‎invariant subspace method and numerical methods‎, ‎\cite{6,5,7,8}‎. Among this‎, ‎the method of characteristics is an efficient and practical method for solving linear fractional differential equations (FDEs) of multi-order‎. In this paper we apply this method for solving a family of linear (2+1)-dimensional FDE of multi order ‎$‎‎\alpha,\beta$ and ‎‎$\gamma‎‎$‎. https://cmde.tabrizu.ac.ir/article_6807_1f8b6308a4d5f4bb27bd1b83f2252a51.pdf
