Hi everyone. I am Chirantan Chowdhury, a Post Docotoral student in Mathematics at University of Duisburg-Essen, Germany. Welcome to my website.  I am interested in higher category in particular the notion of six functor formalisms and its applications in field of Algebraic geometry, Motivic Homotopy theory and other fields.  I did my PhD at University of Duisburg-Essen under Prof. Dr. Jochen Heinloth.  You shall find my CV and the articles i have in the other sections of the website. Have a nice day and stay positive !!
