On a Riemannian space admitting more than one Sasakian structures

ADMITTING CENTER MAPS ON MULTIPLICATIVE METRIC SPACE

‎In this work‎, ‎we investigate admitting center map on multiplicative metric space‎ ‎and establish some fixed point theorems for such maps‎. ‎We modify the Banach contraction principle and‎ ‎the Caristi's fixed point theorem for M-contraction admitting center maps and we prove some‎ ‎useful theorems‎. ‎Our results on multiplicative metric space improve and modify‎ ‎s...

Ricci Curvature Type Lower Bounds for Sub-riemannian Structures on Sasakian Manifolds

Measure contraction properties are generalizations of the notion of Ricci curvature lower bounds in Riemannian geometry to more general metric measure spaces. In this paper, we give sufficient conditions for a Sasakian manifold equipped with a natural sub-Riemannian distance to satisfy these properties. Moreover, the sufficient conditions are defined by the Tanaka-Webster curvature. This genera...

More than one abortion.

©FFPRHC J Fam Plann Reprod Health Care 2007: 33(3) Introduction The terms ‘repeat abortion’ and ‘repeat aborter’ appear in the scientific literature from the early 1970s onwards. To begin with, the pejorative term ‘abortion recidivism’ was used by some.1 The initial concern appeared to be that women might be using abortion instead of contraception as a means of fertility control, with connotati...

More than One Adam?

From Marco Polo to Richard Nixon, narratives of the encounter between Chinese and Westerners have been defining texts of European cultures and their descendants. Successive but sporadic reports from travellers, missionaries, diplomats, traders and others have provided a model of an alternative way of arranging people, of organizing their lives, of thinking about the state of being human; one th...
