QR-Submanifolds and Almost Contact 3-Structure
Quaternion Kaehler Manifold QR-Submanifold Almost Contact 3-Structure
2010/3/1
In this paper,QR-submanifolds of quaternion Kaehlerian manifolds with \dim n \perp =1 has been considered. It is shown that each QR-submanifold of quaternion Kaehlerian manifold with \dim n \perp =1 i...
In this work a new proof of the fact that the group structure of the Hecke groups is isomorphic to the free product of two cyclic groups of orders 2 and q is given The method used in the proof require...

ADDITIVE GROUP NONSTANDARD MODELS OF Z
2010/3/17
Let \hat{Z} denote the inverse limit of finite cyclic groups and FgZ the group where F is a vector space over Q and + is defined by (a, x)+(b, y)=(a+b, x+y+g(a,b)) for some g: F\times F...
