let $g$ be a group and $pi(g)$ be the set of primes $p$ such that $g$ contains an element of order $p$. let $nse(g)$ be the set of the number of elements of the same order in $g$. in this paper, we prove that the simple group $l_2(p^2)$ is uniquely determined by $nse(l_2(p^2))$, where $pin{11,13}$‎.‎

This paper analyzes the limits of applicability of the time domain surface impedance concept. Numerical results obtained by the boundary element formulation employing time domain surface impedance boundary conditions (SIBCs) of different orders of approximation are compared with experimental data and numerical results obtained using the finite element method. An analytical formula for evaluatio...

We focus here on a class of fourth-order parabolic equations that can be written as system second-order by introducing an auxiliary variable. design novel fully discrete mixed finite element method to approximate these equations. In our approach, we propose new techniques using the backward differentiation formula for time derivative and special technique approximation nonlinear terms. The use ...
