Computation of sharp estimates of the Poincaré constant on planar domains with piecewise self-similar boundary
Lehel Banjai, Lyonell Boulton
We establish a strategy for finding sharp upper and lower numerical bounds of the Poincaré constant on a class of planar domains with piecewise self-similar boundary. The approach…

Tensor FEM for spectral fractional diffusion
Lehel Banjai, Jens M. Melenk, Ricardo H. Nochetto +3
We design and analyze several Finite Element Methods (FEMs) applied to the Caffarelli-Silvestre extension that localizes the fractional powers of symmetric, coercive, linear ellipt…

Runge--Kutta convolution coercivity and its use for time-dependent boundary integral equations
Lehel Banjai, Christian Lubich
A coercivity property of temporal convolution operators is an essential tool in the analysis of time-dependent boundary integral equations and their space and time discretisations.…
