For the Bernstein left quasi-interpolants B (2r-1) n f , we prove that for some k This is a strong converse inequality of type B.
Converse inequalities are proved for a family of operators that state the equivalence of two terms of error in approximation to the revelant modulus of smoothness. Such inequalities have been proved by Z. Ditzian and K. G. Ivanov with a different method. Our emphasis is that these so-called strong c
we present sufficient and necessary conditions SNECs under which equalities occur in those corresponding matrix Kantorovich-type inequalities. We also present several relevant inequalities.
