In this paper, we propose and study a fully discretization for computing the positive and (possibly) blowing-up solution of the Cauchy problem: u t -j 2 x u m = u p 1 in R, where m β (0, 1), p 1 > 1, > 0, with an initial condition u 0 assumed to be a nonnegative and continuous function with compact

In this paper, the work initiated in part one and two is extended to the transient subgrid scale/gradient subgrid scale (SGS/GSGS) stabilized method. Temporal accuracy and stability of semi-discrete and time-discontinuous space-time versions of the method are examined for transient advection-diffusi
of the discretization is then minimized. This idea is called global discretisation where attention is no longer paid to The three-dimensional, time-dependent convection-diffusion equation (CDE) is considered. An exponential transformation is used the individual spatial and temporal derivatives but t
