Certain Properties of Hypergeometric Functions
"... The quotients of certain hypergeometric functions are presented as fractions which converge uniformly in the unit disc. These results lead to the existence of certain hypergeometric functions in the class of either convex functions, PC , or starlike functions PS * . ..."

On certain properties of cosmological models
 Zh. Eksper. Teoret. Fiz
, 1972
"... Abstract. It is shown that in homogeneous cosmological models the Einstein equations can be reduced, on the basis of scale invariance, to systems with friction. The formalism involving friction permits one to investigate the problem of isotropization of the solutions in the Bianchi model IX at late ..."

Let $R $ be a universally continuous semiordered linear space. A functional $m(a)(a\in R) $ is said to be a modularl) on $R $ if it satisfies the following modular conditions: (1) $ 0\leqq m(a)\leqq\infty $ for all $a\in R $; (2) if $m(\xi a)=0 $ for all $\xi>0 $ , then $a=0 $; (3) for any $a\in R $ there exists $a>0 $ such that $ m(aa)<\infty $; (4) for every $a\in R, $ $m(\xi a) $ is a convex function of $\xi $; (5) $a\leqqb $ implies $m(a)\leqq m(b) $; (6) $a\wedge b=\backslash 0 $ implies $m(a+b)=m(a)+m(b) $; (7) $0\leqq a_{l}\uparrow aRC.4 $ implies $m(a)=\sup_{R\in\Lambda}m(a_{\lambda}) $. In $R $ , we define functionals $a, $ $\Verta\Vert(a\in R) $ as follows $a=\inf_{\xi>0}\frac{1+m(\tilde{\sigma}a)}{\xi} $. $\Verta_{1}^{1}=\inf_{m(\text{\’{e}} a)\leq 1}\frac{1}{\xi} $. Then it is easily seen that both $a $ and $\Verta\Vert $ are norms on $R $ and $_{1}a\Vert\leqqa\leqq 2\Verta\Vert $ for all $a\in R $. $a $ is said to be the first norm by $m$ and $\Verta\Vert $ is said to be the second norm by $m $. Let $\overline{R}^{m} $ be the modular

Throughout the paper we use the notations and terminologies used in [2]. Here $w\lim_{\nu\rightarrow\infty}a_{\nu}=a $ or $w\lim_{\nu\rightarrow\infty}a_{\nu}=a $ for $a, $ $a_{\nu}\in R(\nu=1,2,3, \cdots)$ means $\lim_{\nu\rightarrow\infty}\overline{\sigma}(a_{\nu}a)=0 $ or $\lim_{\nu\rightarrow\infty} $ a $(a_{\nu}a)=0 $ respectively for any $\overline{a}\in\overline{R}^{m1)} $. If $\Phi(u) $ is a real convex function, defined for $u\geqq 0 $ , such that $\Phi(0)=0$ and $\Phi(u)\geqq 0 $ for $u>0 $ , but $\Phi(u) $ not identically zero or infinity for $u>0 $,

Approximate Riemann Solvers, Parameter Vectors, and Difference Schemes

It is argued that in existing schemes much of this information is degraded, and that only certain features of the exact solution ..."

It is shown that these features can be obtained by constructing a matrix with a certain “Property U.” Matrices having this property are exhibited for the equations of steady and unsteady gasdynamics. In order to construct them, it is found helpful to introduce “parameter vectors
