“…The computation and the application of Vladimirov's pseudo distance to specific examples may not always be easy and it may demand more work; this, however, may well be a common feature, as, for instance, Brezis-Haraux function and Vladimirov pseudo distance are not completely unrelated. With our techniques and/or results, a number of subsidiary classes of problems may be solved and then applied in different studies and fields; these include second-order evolution inclusions, relaxation and viscosity in control theory, variational inequalities, Skorohod problems and sweeping processes, asymptotic theory, etc; cf., say, [26,12,3,29,30,4,5,15,2].…”
