Weakly close-to-convex-functions

Rocky Mountain Journal of Mathematics, 1988
We obtain coefficient bounds and integral means inequalities for the class of multivalent weakly close to convex functions. We also consider the integral means problem for the subclass of multivalent convex functions. Introduction. Let S(p) denote the class of functions / , analytic in A = { z : | 2 : | 0 so that Re[zf(z)/f(z)} > 0 for 6 0 such ...

Janowski Type q-Convex and q-Close-to-Convex Functions Associated with q-Conic Domain

Mathematics, 2020
Certain new classes of q-convex and q-close to convex functions that involve the q-Janowski type functions have been defined by using the concepts of quantum (or q-) calculus as well as q-conic domain

Fekete-Szego Inequalities for Close-to-Convex Functions [PDF]

Proceedings of the American Mathematical Society, 1993
The author claims to extend work of the reviewer [Proc. Am. Math. Soc. 101, 89-95 (1987; Zbl 0635.35019) and Arch. Math. 49, 89-95 (1987; Zbl 0635.30020)] about the Fekete-Szegő problem of maximizing the functional \(| a_ 3-\mu a_ 2^ 2|\) (\(\mu\in\mathbb{R}\)) for close- to-convex functions of order \(\beta\geq 0\). Unfortunately he does not work with

Colloidal Crack Sintering Lithography for Light‐Induced Patterning of Particle Assemblies

Advanced Functional Materials, EarlyView.
Colloidal crack sintering lithography (CCSL) is a microfabrication technique that uses light‐induced photothermal heating to trigger sintering and controlled cracking in polymer colloidal assemblies. Local structural changes generate microchannels and patterns, enabling direct writing of diverse topographic motifs.

Study of Generalized q-Close-to-Convex Functions Related to Parabolic Domain

Journal of Function Spaces, 2023
The concepts of bounded boundary rotation and parabolic domain are used to define certain new classes of analytic functions such as V1,qm,g, R1,qm,g, T1,qm,g, and Q1,qγm,g,a. The difference of coefficients, necessary conditions, distortion bounds, radius

Spatiotemporal Plasma–Mediated Laser Fabrication of Ultrahigh‐Aspect‐Ratio Nanochannel Arrays for Vertical Perovskite Nanowire Semiconductor Devices

Advanced Functional Materials, EarlyView.
A spatiotemporal plasma–mediated laser processing approach is developed to fabricate ultrahigh–aspect ratio nanochannel arrays and corresponding perovskite nanowire arrays within transparent materials for optoelectronics devices. The laser‐fabricated nanochannels serve as templates for controlled perovskite infiltration and crystallization, enabling ...
