Title: Approximations of the best constants
Speaker: Prof. Liviu Ignat
Affiliation: Institute of Mathematics of the Romanian Academy

Abstract. In this talk we consider some well known quotients related with either eigenvalue problems, Sobolev or Hardy’s inequality. We consider the infimum of these quotients and their discrete analogous in a finite element subspace. We estimate the difference between the best constants above as the discretization parameter goes to zero and obtain sharp convergence rates.
