Displacement energy of unit disk cotangent bundles

, 2013
We give an upper bound of a Hamiltonian displacement energy of a unit disk cotangent bundle $D^*M$ in a cotangent bundle $T^*M$, when the base manifold $M$ is an open Riemannian manifold.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

Advanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Starlikeness Properties of a New Integral Operator for Meromorphic Functions

Journal of Applied Mathematics, 2011
We define here an integral operator ℋ𝛾1,…,𝛾𝑛 for meromorphic functions in the punctured open unit disk. Several starlikeness conditions for the integral operator ℋ𝛾1,…,𝛾𝑛 are derived.

New criteria for Carathéodory functions

Journal of Inequalities and Applications, 2019
The object of the present paper is to investigate various conditions for Carathéodory functions in the open unit disk. Also we give some applications to univalent functions as special cases.

Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

Advanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Radii of Starlikeness Associated with the Lemniscate of Bernoulli and the Left-Half Plane

, 2011
A normalized analytic function f defined on the open unit disk in the complex plane is in the class SL if zf'(z)/f(z) lies in the region bounded by the right-half of the lemniscate of Bernoulli given by |w^2 - 1| < 1. In the present investigation, the SL-

Inequalities for Lorentz polynomials [PDF]

, 2014
We prove a few interesting inequalities for Lorentz polynomials including Nikolskii-type inequalities. A highlight of the paper is a sharp Markov-type inequality for polynomials of degree at most n with real coefficients and with derivative not vanishing

Various operators in relation to fractional order calculus and some of their applications to normalized analytic functions in the open unit disk

TURKISH JOURNAL OF MATHEMATICS, 2021
Summary: The main object of this scientific work is firstly to introduce various operators of fractional calculus (that is that fractional integral and fractional derivative(s)) in certain domains of the complex plane, then to determine certain results correlating with normalized analytic functions, which are analytic in certain domains in the complex ...
