A Class of k-Symmetric Harmonic Functions Involving a Certain q-Derivative Operator
In this paper, we introduce a new class of harmonic univalent functions with respect to k-symmetric points by using a newly-defined q-analog of the derivative operator for complex harmonic functions.

On Some Classes of Harmonic Functions Associated with the Janowski Function
In this paper, we introduce some classes of univalent harmonic functions with respect to the symmetric conjugate points by means of subordination, the analytic parts of which are reciprocal starlike (or convex) functions.

NEW CLASSES OF HARMONIC UNIVALENT FUNCTIONS
Summary: We define and investigate new classes of harmonic univalent functions defined by Sălăgean integral operator, denoted by \(H(m,n,\alpha,\beta)\) and \(H^-(m,n,\alpha,\beta)\). We obtain coefficient inequalities and distortion bounds for the functions in the class \(H(m,n, \alpha,\beta)\).

ON REGULARITY THEOREMS FOR LINEARLY INVARIANT FAMILIES OF HARMONIC FUNCTIONS
The classical theorem of growth regularity in the class S of analytic and univalent in the unit disc ∆ functions ƒ describes the growth character of different functionals of ƒ Є S and z Є ∆ as z tends to δ∆.

Halide Perovskite: A Rich Source of Thermal Insulator
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 ...

Certain New Class of Harmonic Functions Involving Quantum Calculus
Here in this paper, we are using the concepts of q-calculus operator theory associated with harmonic functions and define the q-Noor integral operator for harmonic functions f∈H0. We investigate a new class SH0m,q,α of harmonic functions f∈H0.
