Typically real logharmonic mappings
International Journal of Mathematics and Mathematical Sciences, 2002 We consider logharmonic mappings of the form f(z)=z|z| 2βhg¯ defined on the unit disk U which are typically real. We obtain representation theorems and distortion theorems.

A new subclass of close-to-convex functions [PDF]
Surveys in Mathematics and its Applications, 2016 In this work, we introduce and investigate an interesting subclass Xt(γ) of analytic and close-to-convex functions in the open unit disk U. For functions belonging to the class Xt(γ), we drive several properties including coefficient estimates ...

Mitigation of welding distortion and residual stresses via cryogenic CO2 cooling - a numerical investigation [PDF]
, 2008 Fusion welding remains the most common and convenient fabrication method for large, thinplate welded structures. However, the resulting tendency to out-of-plane distortion exacts severe design and fabrication penalties in terms of poorer buckling ...

Prestarlike functions with negative coefficients
International Journal of Mathematics and Mathematical Sciences, 1979 The extreme points for prestarlike functions having negative coefficients are determined. Coefficient, distortion and radii of univalence, starlikeness, and convexity theorems are also obtained.

Remarks on James's distortion theorems [PDF]
Bulletin of the Australian Mathematical Society, 1998 If a Banach space X contains a complemented subspace isomorphic to c0 (respectively, ℓ1), then X contains complemented almost isometric copies of c0 (respectively, ℓ1). If a Banach space X is such that X* contains a subspace isomorphic to L1[0, 1] (respectively, ℓ∞), then X* contains almost isometric copies of L1[0, 1] (respectively, ℓ∞).

Close-to-starlike logharmonic mappings
International Journal of Mathematics and Mathematical Sciences, 1996 We consider logharmonic mappings of the form f=z|z|2βhg¯ defined on the unit disc U which can be written as the product of a logharmonic mapping with positive real part and a univalent starlike logharmonic mapping.

On conformal distortion and Sullivan’s sector theorem [PDF]
Proceedings of the American Mathematical Society, 1998 Using general bounds on the conformal distortion of univalent maps, we prove a strong version of Sullivan’s sector theorem, which gives certain sufficient conditions for an arbitrarily long composition of univalent Herglotz functions to map the upper half-plane into a proper sub-sector.

Distortion theorems for Bloch functions [PDF]
Pacific Journal of Mathematics, 1997 This paper is a continuation of the authors' earlier investigation [see \textit{M. Bonk, D. Minda} and \textit{H. Yanagihara} [J. Anal. Math. 69, 73-95 73-95 (1996; Zbl 0874.30026)] of distortion theorems for Bloch functions. A holomorphic function \(f\) defined on the unit disk \(D\) is called a Bloch function if \[ \|f\|_B= \sup\biggl \{\bigl(1- |z |^
