[ 1 ] - تقارن جواب بهین برای دامنه‌ای متقارن
در این مقاله یک مساله بیشینه سازی وابسته به یک معادله لاپلاسین با شرط مرزی دیریکله را، روی دسته تجدید آرایش های یک تابع نامنفی، در نظر می‌گیریم. وقتی دامنه‌ی معادله متقارن باشد، تحت شرایط خاص، ثابت می‌کنیم که جواب بهین مساله ماکزیمم سازی وابسته به آن نیز متقارن خواهد بود. همچنین نشان می‌دهیم که جواب بهین یکتاست.
[ 2 ] - Solution of Troesch's problem through double exponential Sinc-Galerkin method
Sinc-Galerkin method based upon double exponential transformation for solving Troesch's problem was given in this study. Properties of the Sinc-Galerkin approach were utilized to reduce the solution of nonlinear two-point boundary value problem to same nonlinear algebraic equations, also, the matrix form of the nonlinear algebraic equations was obtained.The error bound of the method was found. ...
[ 3 ] - A numerical treatment of a reaction-diffusion model of spatial pattern in the embryo
In this work the mathematical model of a spatial pattern in chemical and biological systems is investigated numerically. The proposed model considered as a nonlinear reaction-diffusion equation. A computational approach based on finite difference and RBF-collocation methods is conducted to solve the equation with respect to the appropriate initial and boundary conditions. The ability and robust...
[ 4 ] - Solution of Troesche's problem by double exponential Sinc collocation method
In this investigation, the Sinc collocation method based on double exponential transformation is developed to solve the Troesche's problem. Properties of this method are utilized to reduce the system of strongly nonlinear two point boundary value problem to same nonlinear algebraic equations. Combining double exponential transformation through Sinc collocation method causes the remarkable resul...
