2018 **Abstract:** Based on the locally one-dimensional strategy, we propose two high order finite difference schemes for solving two-dimensional linear parabolic equations. In the first method, fourth order approximation in space and (2, 2) Padé formula in time are considered. These lead to a fourth order finite difference scheme in both space and time. For the second method, we employ sixth order approximation in space and (3, 3) Padé formula in time. This yields a novel sixth order scheme in both space and time. The methods a…

“…Compact scheme is used in solving coupled Burgers' equation in [6]. Also, [7] proposes two high order finite difference schemes for solving twodimensional linear parabolic equations where fourth order compact schemes were considered. Also, [8] derived the compact theta scheme for the linear initial-boundary value problems, while [9] formulated a fourth order compact scheme that satisfies the Lie symmetry.…”

“…In this method, the alternating directions implicit (ADI) approach, the Crank-Nicolson discretization and the Richardson extrapolation are used [10]. In [11] the Grünwald finite difference approximation is used for the fractional derivative with ADI method and locally one dimensional (LOD) method is used in [12][13][14][15][16]. In this study, we consider the two dimensional time fractional diffusion equation of the form [9] , , =…”
