چکیده
In Musilak-Orlicz type spaces ${\mathcal S}_{\bf M}$, direct and inverse approximation theorems are obtained in terms of the best approximations functions generalized moduli smoothness. The question exact constants Jackson-type inequalities is studied.

Anisotropic interpolation theorems of Musielak-Orlicz type
*Correspondence: [email protected] College of Mathematics and System Science, Xinjiang University, Urumqi, 830046, P.R. China Abstract Anisotropy is a common attribute of Nature, which shows different characterizations in different directions of all or part of the physical or chemical properties of an object. The anisotropic property, in mathematics, can be expressed by a fairly general discret...

Some approximation theorems involving the modular convergence, which improve known density results of interest in the existence theory for strongly nonlinear boundary value problems are presented.
متن کاملApproximation in Smirnov spaces: Direct and inverse theorems
We give direct and inverse approximation theorems for Dirichlet series in Smirnov spaces over convex polygons. We estimate the degree of convergence and the regularity of the functions with moduli of arbitrary order k. Moreover, we consider the influence of differentiability conditions on the rate of approximation and vice versa. This work extends results by Yu. I. Mel’nik and gives an example ...

and Applied Analysis 3 Proposition 1.2. Function σ t is μ-measurable. Proof. Pick a dense set {ri}i 1 in 0,∞ and set Bk { t ∈ T : M ( t, 1 2 rk ) 1 2 M t, rk } , qk t rkχBk t k ∈ N . 1.7 It is easy to see that for all k ∈ N, σ t ≥ qk t μ-a.e on T . Hence, supk≥1qk t ≤ σ t . For μ-a.e t ∈ T , arbitrarily choose ε ∈ 0, σ t . Then, there exists rk ∈ σ t − ε, σ t such that M t, 1/2 rk 1/2 M t, rk ,...
متن کاملNotes on approximation in the Musielak-Orlicz sequence spaces of multifunctions
We introduced the notion of (X, dist,V)-boundedness of a filtered family of operators in the Musielak-Orlicz sequence space Xφ of multifunctions. This notion is used to get the convergence theorems for the families of X-linear operators, X-distsublinear operators and X-dist-convex operators. Also, we prove that Xφ is complete.
