Hi everyone. I am Chirantan Chowdhury, a Ph.D student in Mathematics at University of Duisburg-Essen, Germany. Welcome to my website.  I am mainly interested in complex geometry, algebraic geometry and category theory.  I shall post  a "variety" of articles which include lecture notes and my own understanding of  the respective topics.  I am also a lover of movies and tv series. There shall be a link where I shall share my own reviews of  movies and TV series.
