DOI: 10.1109/tap.2018.2817287
Abstract: A novel approach based on the singularity cancellation (SC) is proposed to accurately and efficiently evaluate the singular integrals arising in the integral equation discontinuous Galerkin (IEDG) method. Since IEDG employs the half-RWG basis function… read more here.

DOI: 10.3934/eect.2020007
Abstract: In this work, we consider the three-dimensional viscoelastic fluid flow equations, arising from the motion of Kelvin-Voigt fluids in bounded and unbounded domains. We investigate the global solvability results, asymptotic behavior and also address some… read more here.
