SIAM Journal on Numerical Analysis, Vol. 54, No. 4 (2016), pp. 2619-2639 (21 pages) We study a discretization technique for the parabolic fractional obstacle problem in bounded domains. The fractional ...
The stress-displacement-pressure formulation of the elasticity problem may suffer from two types of numerical instabilities related to the finite element interpolation of the unknowns. The first is ...
