Annual Progress Seminar
Speaker: Aratrika Pandey (IIT Bombay)
Host: Ravi Raghunathan
Title: Exact Approximation in the field of formal series
Time, day and date: 4:00:00 PM, Monday, February 24
Venue: Ramanujan Hall
Abstract: We prove a lower bound for the Hausdorff dimension of the set
of exactly $\psi$-approximable matrices with values in a local field of
positive characteristic. This is the analogue of the corresponding
theorem of Bandi and de Saxc\'e over the reals, and is a higher
dimensional version of a theorem.
