We determine the Hopf Galois structures on a field extension of degree twice an odd prime square and classify corresponding skew left braces. Besides we separable extensions allowing cyclic structure number these structures.

This paper shows that the weighting coefficient matrices of the differential quadrature method (DQM) are centrosymmetric or skew-centrosymmetric if the grid spacings are symmetric irrespective of whether they are equal or unequal. A new skew centrosymmetric matrix is also discussed. The application of the properties of centrosymmetric and skew centrosymmetric matrix can reduce the computational...

In this paper, the inverse gamma power series (IGPS) class of distributions asymmetric is introduced. This family obtained by compounding and distributions. We present density, survival hazard functions, moments order statistics IGPS. Estimation first discussed means quantile method. Then, an EM algorithm implemented to compute maximum likelihood estimates parameters. Moreover, a simulation stu...

Quantifying dependence between extreme values is a central problem in many theoretical and applied studies. The main distinction is between asymptotically independent and asymptotically dependent extremes, with important theoretical examples of these general limiting classes being the extremal behaviour of a bivariate Normal distribution, for asymptotic independence, and of the bivariate t dist...
