learn quantum field theory and thermal field theory. I thank them all. I express my gratitude to all members of the Theory Group for their help and cooperation. The Research Fellows, in particular, have helped me in every possible way during my stay here. Last, but not the least, I thank my mother for her support and understanding, without which this work could not have been done.

This essay explores religion’s need for law, comparing the story told in Mitra Sharafi’s Law and Identity in Colonial South Asia (2014)—about the virtual hijacking of British colonial law to serve the communal religious needs of Parsis in colonial India—to other contexts in which secular and religious legal systems have built symbiotic relationships, including in the United States and Thailand....

We explore via linearized perturbation theory the Gregory-Laflamme instability of the black string solutions of Einstein’s equations with negative cosmological constant recently discussed in literature. Our results indicate that the black strings whose conformal infinity is the product of time and S × S are stable for large enough values of the event horizon radius. All topological black string...

Introduction Over the years, the use of computer has become an integral part of education and its impact on teaching and learning is widely accepted (Mitra et al, 2000). The successful integration of computers in educational environments depends, to a great extent, on students’ attitudes towards them (Palaigeorgiou, Siozos, Konstantakis & Tsoukalas, 2005). Computer attitude has been defined as ...

To improve and refine a player's basketball skills which are crucial for enhancing the quality of play, it is essential to improve the athletic skills that allow him to elevate his play to a higher level. Athletic skills include variables such as speed, power, endurance, agility, coordination, balance and reaction time that contribute to the total development of the player. The level at which b...

The literature on volatility modelling and option pricing is a large and diverse area due to its importance and applications. This paper provides a review of the most significant volatility models and option pricing methods, beginning with constant volatility models up to stochastic volatility. We also survey less commonly known models e.g. hybrid models. We explain various volatility types (e....
