Polynomial-time preprocessing is a simple algorithmic strategy which has been
widely employed in practice to tackle hard problems. The quantification and
analysis of the efficiency of preprocessing algorithms are, in a ...
In this thesis, the parameterized framework is used for the design and analysis
of algorithms for NP-complete problems. This amounts to studying the parameterized
version of the classical decision version. Herein, the ...
In this thesis, to each Borel-de Siebenthal discrete series representation of G(0), the author would associate a holomorphic discrete series representation of K*(0). The main aim of the thesis is to compare the restrictions ...
Petri nets are a formal model of concurrent systems. They were first defined by Petri in
his thesis [Pet62] and were presented at the IFIP 1962 congress in Munich [Pet63]. Nets
are widely used in modelling various aspects ...
This report consists of the materials that is presented in a course of lectures on advanced topics in the theory of gravitation,
at the Institute of Mathematical Sciences, Madras, during the year 1971. The prerequisites ...
The idea behind the dispersion relation is as follows: A Physically significant function such as the scattering amplitude is considered, which is in general a function of the real variable k(momentum) and 'theta' (the ...
These lectures were given by Professor K. Symanzik, Visiting Professor from Graduate School of Arts and Science, New York University, and for which the notes were prepared by K. Venkatesan and T.K. Radha. QED(Quantum ...
This is a series of 12 introductory lectures on Regge Poles and their role in high-energy diffraction scattering, during the academic year 1962-1963. Lecture I is a general introduction to the idea of complex angular ...
The objectives of these lectures aims to provide a systematic development of essential features of elementary particle theory from pure S-matrix principle. Some of the basic relationships of tensor and spinor analysis are ...
This report aims to obtain nonperturbative solutions, with the 'self-consistent' method of approximation. First an indefinite value is assumed for some physical quantity. Then this quantity is calculated using the given ...
The problem considered here is that of describing free particles and antiparticles of definite nonzero mass m, spin s = 0, 1/2, 1, 3/2 and with internal symmetry. The particle is described by a wave function, the basis ...
The author is a student of II year B.Sc, Mathematics, Vivekananda College, Madras University. This report comprises the lectures delivered at Matscience, based on his research work during and after the tenure as a visiting ...
This report is based on a series of lectures delivered at Matscience during April - May 1969. These notes desribes in detail the basics in Fortran Language(FORTRAN II), which is acceptable to IBM 1620, IBM 1130 in Chennai, ...
These lectures were delivered by the Visiting Scientist A. Fujii, a CSIR Visitor, from Department of Physics, School of Science and Technology, Sophia University, Tokyo, Japan. Notes prepared by T.S. Santhanam, Matscience. ...
Lectures Given by Prof.E.C.G. Sudarshan during Summer 1962, and lecture Notes were prepared by Dr.T.K.Radha, Dr. Thunga Satyapal and Mr. K. Raman, IMSc., Chennai.
Collision processes between elementary particles are mathematically described by functions depending on several points of space-time, or of the momentum space. Those, so called n-point functions or rather the generating ...
