Abstract
In this paper we prove convergence and error estimates for the so-called 3-field formulation using piecewise linear finite elements stabilized with boundary bubbles. Optimal error bounds are proved in L^2 and in the broken H^1 norm for the internal variable u, and in suitable weighted L^2 norms for the other two interface variablesFile in questo prodotto:
