“…Problems of non-local type include chemical diffusion, thermoelasticity, heat conduction processes, population dynamics, inverse problems, control theory and certain biological processes (see [3,4,[6][7][8]14,19,16,21,22]). …”
“…The existence, uniqueness and continuous dependence on data of the solution of this non-local boundary-value problem and some other similar problems have been studied in Bouziani (1997Bouziani ( , 1999, Cannon et al (1990) and Cannon and Yin (1989). Also, the interested reader can see Cannon (1984), Day (1992), Friedman (1986), Lepin and Myshkis (1997), Mesloub (2008) and Wang and Lin (1990). In recent years, the development of computational techniques for solving the non-local boundary-value problems has been an important research topic in many areas of applied science and engineering.…”
Purpose -The purpose of this paper is to implement the Ritz-Galerkin method in Bernstein polynomial basis to give approximation solution of a parabolic partial differential equation with non-local boundary conditions. Design/methodology/approach -The properties of Bernstein polynomial and Ritz-Galerkin method are first presented, then the Ritz-Galerkin method is utilized to reduce the given parabolic partial differential equation to the solution of algebraic equations. Illustrative examples are included to demonstrate the validity and applicability of the new technique. Findings -The authors applied the method presented in this paper and solved three test problems. Originality/value -This is the first time that the Ritz-Galerkin method in Bernstein polynomial basis is employed to solve the model investigated in the current paper.
