In this paper, we have considered some properties of quasi-umbilical hypersurfaces of a Riemannian space and obtained a characteristic of Riemannian spaces admi
In this paper, we are concerned with the Cauchy problem:in D_q~α. We got some existence and asymptotic results of their global solutions. Additionally, we got
In this paper, it is proved that the following boundary value problem admits infinitely many solution for 0【λ【λ<sub>1</sub>, n≥5 and for ball regions Ω=B<
