摘要：
This contribution presents a general numerical method for computing lower and upper bound of the optimal constant in Friedrichs' inequality. The standard Rayleigh-Ritz method is used for the lower bound and the method of a priori-a posteriori inequalities is employed for the upper bound. Several numerical experiments show applicability and accuracy of this approach.
