From 4:30 to 5 pm on Tuesday 23 December 2025, our Department of Mathematics PhD student Mr. Jasarat Gasimov will deliver a seminar entitled "The Calderón Problem". He will present a classic inverse problem from PDE theory, related to the Schrödinger equation: weak solutions, well-posedness, and uniqueness. All are welcome to attend the talk in ASG11 (ASA2), and refreshments will be provided.
