Research Interests
My interests, broadly, lie in Algebra, Topology and Geometry. My studies so far have revolved around Lie and Topological groups, with an interplay of representation theory, differential geometry and algebraic topology.
Educational Qualifications
2012 - 2017 Five years Integrated Dual B.S. - M.S.
DISCIPLINE Mathematical Sciences
THESIS The master's thesis was titled Maximal torus in a Lie group and its Weyl group .
It was a study of Lie groups- starting from the basics, and up till the maximal torus in compact connected Lie groups. The main result studied was the Conjugation theorem of Maximal Tori, primarily following the text by Theodor Brocker and Tammo tom Dieck on the subject, along with J.P. Serre's articles in Seminaire Sophus Lie}.

2017 - 2018
BREAK YEAR I took a break after completing my MS due to health problems. During the two years of my MS, I was suffering from some problems related to chronic sleep issues, fatigue and a form of IBS (Inflammatory Bowel Syndrome). Although the problem wasn't severe yet its nature was chronic, so I was informed by the doctor that it should be treated slowly over a long treatment gradually. Therefore I took a break from the mid of 2017 to mid of 2018 during which I had the treatment. After that I decided to do a project before applying for a PhD - the details of which are as mentioned below.
2018 - 2019
PROJECT Root Systems, Weyl Character Formula and Spin groups.
This project followed up on the thesis, studying the representations of compact Lie groups. It began with a recall of representation theory with an introduction to weights and roots. Later, the Root systems were covered in detail, including the Dynkin diagrams and the fundamental groups of compact Lie groups. Finally, the Weyl Character Formula was covered. This was followed by computations for the case of the classical Lie groups using the WCF. Afterwards, Clifford algebras and the Spin groups were studied using the lecture notes by B. Conrad and R. Borcherds and later the text by Brocker and Dieck was followed for the calculation of its maximal torus, Weyl group, root system and, finally the application of WCF to compute its representations.

CURRENT After its completion, I was directed by Dr. Datta to study Algebraic topology, with the aim to study Poincare Duality because of its importance in the study of geometry and topology. The book by Allen Hatcher is being followed. The study started with Homology theory- Simplicial, Singular and Cellular homology. It also included some of its classical applications such as Borsuk-Ulam theorem and Lefshetz fixed point theorem. After its completion, the study is moving to Cohomology.
Research Experience
AUG. 2011 - JUL. 2012 Visiting Student Research Programme 2016
SUPERVISOR Dr. Sandeep Varma, Tata Institute for Fundamental Research (TIFR) Mumbai, India.
ABSTRACT A version of Peter Weyl Theorem for compact quotients.
The project was a study of the representations of Topological groups. It starting with the necessary preliminaries, such as a proof of the existence of Haar measure on locally compact topological groups, and the Hilbert space theory. Afterwards, the notes by Paul Garett- Unitary Representations of Topological groups was followed, from the start till the section number 22, where we concluded with the Peter Weyl Theorem- a version for the compact quotients of locally compact topological groups.
AUG. 2011 - JUL. 2012 Student Project 2015
SUPERVISOR Dr. Neena Gupta, Indian Statistical Institute, Kolkata, India.
ABSTRACT Commutative Algebra.
The project was a study in Commutative Algebra, which comprised of the continuation of the Ring theory course from the previous semester, using the text Introduction to commutative Algebra by Atiyah and Macdonald. The topics covered were Rings, Ideals and Module theory.
AUG. 2011 - JUL. 2012 Student Research Fellowship Programme 2014
SUPERVISOR Prof. A. J. Parameswaran, TIFR Mumbai, India.
ABSTRACT Linear and Homological Algebra.
The project involved the study of the linear and abstract algebraic structures with some elements of multilinear algebra following the classic text on the subject Finite Dimensional Vector Spaces by Paul R Halmos and the TIFR pamphlet in mathematics Algebraic Topology. Further, the pamphlet Homological Methods in Commutative Algebra was referred for some applications of linear algebra to Homology such as the Euler Characteristics.
