In this paper we propose the q analogues of modified Baskakov-Sz ′asz op-erators. We estimate the moments and established direct results in term of modulus of
More recently, a variational approach has been proposed by Lin and Wang for damping motion with a Lagrangian holding the energy term dissipated by a fric-tion f
In this paper we establish sharp H ¨older estimates of harmonic functions on a class of connected post critically finite (p.c.f.) self-similar sets, and show t
