Using the tadpole improved Wilson quark action on small, coarse, and anisotropic lattices, meson-meson scattering lengths are calculated within quenched approxi
In this article, we study the (2+1)-extension of Burgers equation and the KP equation. At first, based on a known Backlund transformation and corresponding Lax
We study space-time transformations of the time-dependent Schrōdinger equation (TDSE) with time- and position-dependent (effective) mass. We obtain the most ge
