Lipschitz classes on local fields

Science in China Series A: Mathematics, 2007
The Lipschitz class Lipα on a local field K is defined in this note, and the equivalent relationship between the Lipschitz class Lipα and the Holder type space C α (K) is proved. Then, those important characteristics on the Euclidean space R n and the local field K are compared, so that one may interpret the essential ...

Generalized Lipschitz Classes and Fourier Coefficients

Mathematical Notes, 2004
The author proves several general results. Among others he gives a criterion for a function to belong to the generalized Lipschitz class defined by using moduli of smoothness of positive orders and presents necessary and sufficient conditions for this criterion to hold.

Duality for General Lipschitz Classes and Applications

Proceedings of the London Mathematical Society, 1997
As shown by the author in Proc. Am. Math. Soc. 115, 345-352 (1992; Zbl 0768.46012), for every metric space \((K,d)\) with compact closed balls one has \((\text{lip }\varphi(K))^{**}= \text{Lip }\varphi(K)\), where \(\varphi\) is any majorant (i.e., nondecreasing function on \(\mathbb{R}_+\) with \(\varphi(0+)= \varphi(0)=0\) such that \(\varphi(t)/t ...

Fourier transforms in generalized Lipschitz classes

Proceedings of the Steklov Institute of Mathematics, 2013
We obtain sufficient conditions for the Fourier transform of a function f ∈ L1(ℝ) to belong to generalized Lipschitz classes defined by the modulus of smoothness of order m. The sharpness of these conditions is established in the cases when f(t) ≥ 0 on ℝ or tf (t) ≥ 0 on ℝ.

Weak interpolation for the lipschitz class

Mathematica Slovaca, 2017
Abstract We introduce and characterize interpolation sets in a weak sense for the Lipschitz class in the unit disc of the complex plane. Interpolation sets in the classical sense and in a strong sense for this space have already been examined.
