a numerical investigation on the effect of the fractional operators in analyzing the brain tumors

A mathematical model of brain tumor which is an extension of a twodimensional mathematical model of glioma growth and diffusion, is considered in thisletter. a numerical approach based on operational matrix of bernoulli polynomials isused to estimate the solution of this model. using this technique, the problem underthe study is converted to a system of nonlinear algebraic equations which can be solvedvia newton’s method. finally, test problem is included to confirm the accuracy andefficiency of the suggested method.
