Properties of utility function for Barles and Soner model
(University of Tabriz, 2019-01-01)The nonlinear Black-Scholes equation has been increasingly attracting interest over the last two decades, because it provides more accurate values by considering transaction costs as a viable assumption. In this paper we ...

On the solving of matrix equation of Sylvester type
(University of Tabriz, 2019-01-01)A solution of two problems related to the matrix equation of Sylvester type is given. In the first problem, the procedures for linear matrix inequalities are used to construct the solution of this equation. In the second ...

Multi-soliton of the (2+1)-dimensional Calogero-Bogoyavlenskii-Schiff equation and KdV equation
(University of Tabriz, 2019-01-01)A direct rational exponential scheme is offered to construct exact multi-soliton solutions of nonlinear partial differential equation. We have considered the Calogero–Bogoyavlenskii–Schiff equation and KdV equation as two ...

The numerical values of the nodal points for the Sturm-Liouville equation with one turning point
(University of Tabriz, 2019-01-01)An inverse nodal problem has first been studied for the Sturm-Liouville equation with one turning point. The asymptotic representation of the corresponding eigenfunctions of the eigenvalues has been investigated and an ...

Stable Gaussian radial basis function method for solving Helmholtz equations
(University of Tabriz, 2019-01-01)Radial basis functions (RBFs) are a powerful tool for approximating the solution of high-dimensional problems. They are often referred to as a meshfree method and can be spectrally accurate. In this paper, we analyze ...

A new reduced mathematical model to simulate the action potential in end plate of skeletal muscle fibers
(University of Tabriz, 2019-01-01)Usually mathematicians use Hodgkin-Huxley model or FitzHug-Nagumo model to simulate action potentials of skeletal muscle fibers. These models are electrically excitable, but skeletal muscle fibers are stimulated chemically. ...

Finite integration method with RBFs for solving time-fractional convection-diffusion equation with variable coefficients
(University of Tabriz, 2019-01-01)In this paper, a modification of finite integration method (FIM) is combined with the radial basis function (RBF) method to solve a time-fractional convection-diffusion equation with variable coefficients. The FIM transforms ...

Nordsieck representation of high order predictor-corrector Obreshkov methods and their implementation
(University of Tabriz, 2019-01-01)Predictor-corrector (PC) methods for the numerical solution of stiff ODEs can be extended to include the second derivative of the solution. In this paper, we consider second derivative PC methods with the three-step second ...
