The possibility of the unexplained Kolar events, recorded in the 1970s and 1980s, being due to the decays of dark matter particles of mass in the range of 5–10 GeV, is pointed out.

The main contribution of this thesis is in proving upper bounds on the counting complexity of some computational problems that arise from group theory. It consists of two parts. The first part concentrates on studying the ...

This thesis is divided into two parts, and deals with the parameterized complexity analysis of two classes of problems: (i) graph partitioning problems and (ii) crossing minimisation problems. The first of these, graph ...

In this thesis the author had tried to identify the objects that correspond, at large volume to the fractional 2-branes in C^n / ZN orbifolds. The fractional two-branes have a fractional first Chern class and also have ...

Models which regard the decimet B* as a composite of the octet baryons and octet pseudoscalar mesons usually give excessively large SU(3) violations for the B* because of the large mass differences within the baryon octet ...

Let f:Gn,k --> Gm,l be any continuous map between to distinct complex ( resp. quaternionic )Grassmann manifolds of the same dimension. It is shown that the degree of f is zero provided n, m are sufficiently large and ...

This Report consists of the lectures given at the Institute during November 1977, to March 1978, on the applications of density matrix methods to muon capture processes. The reason for the choice of muon capture process ...

We study the process e+e-+X as a possible test to distinguish between fractionally-charged-quark models and gauged integer-charged-quark models. We find that charge-asymmetry measurement in this process would not distinguish ...

We have identified some important and worthwhile physics opportunities with a possible neutrino detector located in India. Particular emphasis is placed on the geographical advantage with a stress on the complimentary ...
