Algebraic formulas for the coefficients of mock theta functions and Weyl vectors of Borcherds products [PDF]

open access: yes, 2017
We present some applications of the Kudla-Millson and the Millson theta lift. The two lifts map weakly holomorphic modular functions to vector valued harmonic Maass forms of weight $3/2$ and $1/2$, respectively.

Three circles theorems for harmonic functions [PDF]

open access: yes, 2016
We proved two three circles theorems for harmonic functions on manifolds in integral sense. As one application, on manifold with nonnegative Ricci curvature, whose tangent cone at infinity is the unique metric cone with unique conic measure, we showed ...

Vector-valued holomorphic and harmonic functions

open access: yesConcrete Operators, 2016
Holomorphic and harmonic functions with values in a Banach space are investigated. Following an approach given in a joint article with Nikolski [4] it is shown that for bounded functions with values in a Banach space it suffices that the composition with

On surface completion and image inpainting by biharmonic functions: Numerical aspects [PDF]

open access: yes, 2018
Numerical experiments with smooth surface extension and image inpainting using harmonic and biharmonic functions are carried out. The boundary data used for constructing biharmonic functions are the values of the Laplacian and normal derivatives of the ...

Harmonic functions associated with Pascal distribution series

open access: yesScientific African, 2023
The primary objective of this paper is to explore the application of a specific convolution operator, which incorporates the Pascal distribution series. Through this investigation, we establish essential inclusion relations between the harmonic class HΥ ...

Harmonic Functions On Manifolds Whose Large Sphere Are Small [PDF]

open access: yes, 2015
We study the growth of harmonic functions on complete Riemann-ian manifolds where the extrinsic diameter of geodesic spheres is sublinear. It is an generalization of a result of A. Kazue. We also get a Cheng and Yau estimates for the gradient of harmonic

Several properties of $$\alpha $$α-harmonic functions in the unit disk [PDF]

open access: yes, 2016
The aim of this paper is to obtain the Schwarz–Pick type inequality for $$\alpha $$α-harmonic functions f in the unit disk and get estimates on the coefficients of f.

Some inequalities for strongly $(p,h)$-harmonic convex functions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
In this paper, we show that harmonic convex functions $f$ is strongly $(p, h)$-harmonic convex functions if and only if it can be decomposed as $g(x) = f(x) - c (\frac{1}{x^p})^2,$ where $g(x)$ is $(p, h)$-harmonic convex function.

Eichler integrals and harmonic weak Maass forms [PDF]

open access: yes, 2013
Recently, K. Bringmann, P. Guerzhoy, Z. Kent and K. Ono studied the connection between Eichler integrals and the holomorphic parts of harmonic weak Maass forms on the full modular group.
