Mappings of finite distortion: sharp Orlicz-conditions.

Janne Kauhanen, Pekka Koskela, Jan Malý, Jani Onninen, Xiao Zhong (2003)

Revista Matemática Iberoamericana

We establish continuity, openness and discreteness, and the condition (N) for mappings of finite distortion under minimal integrability assumptions on the distortion.

Markov convexity and local rigidity of distorted metrics

Manor Mendel, Assaf Naor (2013)

Journal of the European Mathematical Society

It is shown that a Banach space admits an equivalent norm whose modulus of uniform convexity has power-type p if and only if it is Markov p -convex. Counterexamples are constructed to natural questions related to isomorphic uniform convexity of metric spaces, showing in particular that tree metrics fail to have the dichotomy property.

Mathematical treatment for thermoelastic plate with a curvilinear hole in S-plane

Alaa A. El-Bary (2006)

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

The Cauchy integral method has been applied to derive exact and closed expressions for Goursat's functions for the first and second fundamental problems for an infinite thermoelastic plate weakened by a hole having arbitrary shape. The plate considered is conformally mapped to the area of the right half-plane. Many previous discussions of various authors can be considered as special cases of this work. The shape of the hole being an ellipse, a crescent, a triangle, or a cut having the shape of a...

Maximal real Schottky groups.

Rubén A. Hidalgo (2004)

Revista Matemática Iberoamericana

Let S be a real closed Riemann surfaces together a reflection τ : S ---> S, that is, an anticonformal involution with fixed points. A well known fact due to C. L. May asserts that the group K(S, τ), consisting on all automorphisms ...

Maximally convergent rational approximants of meromorphic functions

Hans-Peter Blatt (2015)

Banach Center Publications

Let f be meromorphic on the compact set E ⊂ C with maximal Green domain of meromorphy E ρ ( f ) , ρ(f) < ∞. We investigate rational approximants r n , m of f on E with numerator degree ≤ n and denominator degree ≤ mₙ. We show that a geometric convergence rate of order ρ ( f ) - n on E implies uniform maximal convergence in m₁-measure inside E ρ ( f ) if mₙ = o(n/log n) as n → ∞. If mₙ = o(n), n → ∞, then maximal convergence in capacity inside E ρ ( f ) can be proved at least for a subsequence Λ ⊂ ℕ. Moreover, an analogue of Walsh’s...
