Median time to first decisionApproximate controllability of general impulsive stochastic systems with effects in infinite dimension
In this research, we investigated the feasibility of approximate control for nonlinear impulsive stochastic differential systems defined over infinite-dimensional domains. Our approach is based on the assumption that the associated linear systems are controllable. To this end, we established sufficient ...
Solving first-order systems of linear hyperbolic partial differential equations using fast Fourier transform
In this paper, we address the exact solution of the general first-order systems of linear hyperbolic partial differential equations using the Fourier transformation technique. This transformation converts the system from the physical domain into a system of first-order ordinary differential equations ...
A comparison between decay rate of rationals to ζ(3) and ζ(5)
In this paper we compare numerically some methods of the approximation of zeta (3) and zeta (5) by rationals. The comparison is based on the decay rate of the errors when the series of rationals approximating such zeta values are truncated to a given order N. Several numerical results are also given.
