Extremal properties of extreme and support points of univalent functions with montel normalization
, 2008 Let U = {z : vertical bar z vertical bar < 1} be the unit disk. The Montel class, M(a), is the class of functions f (z) = a(1)z + a(2)z(2) +..., which are analytic and univalent in the unit disk and satisfy the conditions f (0) = 0 and f (a) = a, (0 ...

On the definition of a close-to-convex function
International Journal of Mathematics and Mathematical Sciences, 1978 The standard definition of a close-to-convex function involves a complex numerical factor eiβ which is on occasion erroneously replaced by 1. While it is known to experts in the field that this replacement cannot be made without essentially changing the ...

Halide Perovskite: A Rich Source of Thermal Insulator
Advanced Science, EarlyView.Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

On Littlewood’s conjecture for univalent functions [PDF]
Proceedings of the American Mathematical Society, 1982 The uniform asymptotic theory of functionals on S S is investigated. We prove that Littlewood’s conjecture is equivalent to

Advanced Science, EarlyView.A flexible PDMS‐LATP polymer‐ceramic membrane creates lithium‐ion “superhighways” for rapid and selective extraction from complex brines. The amorphous PDMS matrix suppresses nonselective leakage and stabilizes the ceramic network, while LATP provides preferential Li+ conduction.

A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers
Advanced Science, EarlyView.Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...

A Note on Neighbourhoods of Univalent Functions [PDF]
Proceedings of the American Mathematical Society, 1983 Using a notion of neighbourhood of analytic functions due to Stephan Ruscheweyh we examine conditions under which neighbourhoods of a certain class of convex functions are included in a class of starlike functions.
