in this paper we give some general results on the non-splitextension group $overline{g}_{n} = 2^{2n}{^{cdot}}sp(2n,2), ngeq2.$ we then focus on the group $overline{g}_{4} =2^{8}{^{cdot}}sp(8,2).$ we construct $overline{g}_{4}$ as apermutation group acting on 512 points. the conjugacy classes aredetermined using the coset analysis technique. then we determine theinertia factor groups and fischer...

The Gallai–Ramsey number $$gr_{k}(K_{3}: H_{1}, H_{2}, \cdots , H_{k})$$ is the smallest integer n such that every k-edge-colored $$K_{n}$$ contains either a rainbow $$K_3$$ or monochromatic $$H_{i}$$ in color i for some $$i\in [k]$$ . We define star-critical $$gr_{k}^{*}(K_3: as s $$K_{n}-K_{1, n-1-s}$$ When $$H=H_{1}=\cdots =H_{k}$$ we simply denote $$gr_{k}^{*}(K_{3}: by H)$$ determine numbe...

Let C be a complex field, H_{m_1m_2} linear space of tensor products Hermite matrices H_{m_1}&amp;otimes;H_{m_2} over , and suppose m_{1}, m_2&amp;ge;2 are positive integers. A map f :H_{m_1m_2} &amp;rarr; H_n is called inverse preserver if f( X_{1} &amp;otimes;X_{2} )^{-1}= X_{1}&amp;otimes;X_{2}) ^{-1} ) for arbitrary invertible matrix &amp;otimes; X_{2}&amp;isin; H_{m_{1}m_{2}} .The aim this...

‎In our paper [A‎. ‎B‎. ‎M‎. ‎Basheer and J‎. ‎Moori‎, ‎On a group of the form $2^{10}{:}(U_{5}(2){:}2)$] we calculated the inertia factors‎, ‎Fischer matrices and the ordinary character table of the split‎ ‎extension $ 2^{10}{:}(U_{5}(2){:}2)$ by means of Clifford-Fischer‎ ‎Theory‎. ‎The second inertia factor group of $2^{10}{:}(U_{5}(2){:}2)$‎ ‎is a group of the form $2_{-}^{1+6}{:}((3^{1+2}{...

We examine the long-term behavior of strong solutions for wave equation $ \varepsilon(t)u_{tt}-\Delta u_{t}-\Delta u+f(u) = g(x) and obtain time-dependent attractor in \mathcal{H}_{t}^{1} [H^{2}(\Omega)\cap H_{0}^{1}(\Omega)]\times H_{0}^{1}(\Omega) $. Moreover, is bounded H_{0}^{1}(\Omega)]\times[H^{2}(\Omega)\cap H_{0}^{1}(\Omega)]

Given a family of null hypotheses $H_{1},\ldots,H_{s}$, we are interested in the hypothesis $H_{s}^{\gamma}$ that at most $\gamma-1$ these false. Assuming corresponding $p$-values independent, investigating combined valid for testing $H_{s}^{\gamma}$. In various settings which is false, determine $p$-value works well setting. Via simulations, find Stouffer method if uniformly distributed and si...

In this paper, the problems of robust stabilization and$H_{infty}$ control for uncertain stochastic systems withmultiple time delays represented by the Takagi-Sugeno (T-S) fuzzymodel have been studied. By constructing a new Lyapunov-Krasovskiifunctional (LKF) and using the bounding techniques, sufficientconditions for the delay-dependent robust stabilization and $H_{infty}$ control scheme are p...

we call $h$ an $ss$-embedded subgroup of $g$ if there exists a‎ ‎normal subgroup $t$ of $g$ such that $ht$ is subnormal in $g$ and‎ ‎$hcap tleq h_{sg}$‎, ‎where $h_{sg}$ is the maximal $s$-permutable‎ ‎subgroup of $g$ contained in $h$‎. ‎in this paper‎, ‎we investigate the‎ ‎influence of some $ss$-embedded subgroups on the structure of a‎ ‎finite group $g$‎. ‎some new results were obtained.‎
