The NW-SE to WNW-ESE trending faults, having an oblique trend to the Western Ghats have played a significant role in the structural evolution of the basin and have also controlled the facies distribution and stratigraphy of the different units. The recent reactivation of the NNW-SSE to N-S trending faults which are presumbly associated with the uplift of the Western Ghats, appear to be responsible for the foundering of the greater part of the offshore basin and for shaping the present day coastline with lateritic terraces. Evidences also indicate that the NE-SW trending fractures have been reactivated recently, affecting even the Quaternary sedimentary cover.- Generalised Gottlieb Groups

In his paper "A certain subgroup of the fundamental group" [4] D. A. Gottlieb introduced a certain subgroup G{X, x0) of the fundamental group n1(X,x0) for every connected CW-complex X and studied the properties of this subgroup.- Hopfian and Co-Hopfian Zero-Dimensional Spaces

The main results proved in this paper are:
(i) The only Hopfian or co-Hopfian objects among compact totally disconnected metrizable spaces are finite discrete spaces.
(ii) Every infinite closed subspace of (IN and hence any infinite closed subspace of N* = βN- N is non-co-Hopfian. However, N* admits an abundance of non-closed subspaces which are simultaneously Hopfian and co-Hopfian.
(iii) There are at least 2C non-homeomorphic compact totally disconnected perfect co-Hopfian spaces which are not rigid.
