Student Differential Geometry Seminar — Spring 2020: The Inhomogeneous ˉ∂-Equation


Meeting times



Welcome to the webpage for the Spring 2020 iteration of the SDGS! This semester, we decided to go for the inhomogenous \(\bar{\partial}\)-equation and its (complex) geometric applications.

More precisely, the goal of this seminar is three-fold: (1) studying bits and pieces of several complex variables (SCV) with an analytic introduction to the \(\bar{\partial}\)-operator, (2) covering some basics in complex differential geometry with a geometric take on the \(\bar{\partial}\)-operator, and then (3) exploring applications of the (\(L^2\) theory) of the \(\bar{\partial}\)-operator to various geometric problems.

Any suggestions are welcome!
