A first order system least squares method for the Helmholtz equation [PDF]
We present a first order system least squares (FOSLS) method for the Helmholtz equation at high wave number k, which always deduces Hermitian positive definite algebraic system.

Matrix methods for radial Schr\"{o}dinger eigenproblems defined on a semi-infinite domain
In this paper, we discuss numerical approximation of the eigenvalues of the one-dimensional radial Schr\"{o}dinger equation posed on a semi-infinite interval.

Some implications of a new definition of the exponential function on time scales
We present a new approach to exponential functions on time scales and to timescale analogues of ordinary differential equations. We describe in detail the Cayley-exponential function and associated trigonometric and hyperbolic functions. We show that the

Solving 2^{nd} order parabolic system by simulations of Markov jump processes [PDF]
There are known methods of approximating the solution of parabolic 2^{nd} order systems by solving stochastic differential equations instead. The main idea is based on the fact that a stochastic differential equation defines a diffusion process ...

A novel stochastic ten non-polynomial cubic splines method for heat equations with noise term
In this paper, a new numerical method for solving a class of stochastic partial differential equations is presented. The proposed method is based on a non-polynomial cubic spline algorithm with an O(h4) local truncation error.

New definitions of exponential, hyperbolic and trigonometric functions on time scales
We propose two new definitions of the exponential function on time scales. The first definition is based on the Cayley transformation while the second one is a natural extension of exact discretizations.

On the exact discretization of the classical harmonic oscillator equation
We discuss the exact discretization of the classical harmonic oscillator equation (including the inhomogeneous case and multidimensional generalizations) with a special stress on the energy integral.
