The constant y in the strengthened Cauchy-Buniakowski-Schwarz (C.B.S.) inequality plays a crucial role in the convergence rate of multilevel iterative methods as well as in the efficiency of a posteriori error estimators, that is in the framework of finite element approximations of S.P.D. problems.
For a class of two-dimensional boundary value problems including diffusion and elasticity problems, it is proved that the constants in the corresponding strengthened Cauchy-Buniakowski-Schwarz (CBS) inequality in the cases of two-level hierarchical piecewise-linear/piecewise-linear and piecewise-lin
