We obtain a sharp result on order of certain affine and linear invariant families of harmonic quasiconformal mappings with bounded Schwarzian norm. This problem is motivated by the work of Chuaqui, Hern\'{a}ndez and Mart\'{i}n [Math. Ann. 367: 1099--

The conjugate function method is an algorithm for numerical computation of conformal mappings for simply and multiply connected domains. In this paper, the conjugate function method is extended to cover conformal mappings between Riemannian surfaces.

We investigate Lindel\"of and Koebe type boundary behavior results for bounded quasiregular mappings in $n$-dimensional Euclidean space. Our results give sufficient conditions for the existence of non-tangential limits at a boundary point.

In this paper, we present a stochastic method for the simulation of Laplace's equation with a mixed boundary condition in planar domains that are polygonal or bounded by circular arcs. We call this method the Reflected Walk-on-Spheres algorithm. The

This paper presents the design, development and characterization of a leaky wave plasma antenna at 2.45 GHz which has potential application in military Wi-Fi, in areas where a continuous change in frequency is required. The design of the cylindrical

Abstract Background A 7.8 R scale earthquake hit Nepal in April 2015 and caused about 9000 deaths along with damage to infrastructure, including the water and sewage system. Bhaktapur was one of the highly affected districts. A typhoid vaccination ca

In this paper, we study positive solutions of the quasilinear elliptic equation $$ Q'_{p,\mathcal{A},V}[u]\triangleq -\dive{\mathcal{A}(x,\nabla u)}+V(x)|u|^{p-2}u=0, $$ in a domain $\Gw\subseteq \R^n$, where $n\geq 2$, $1

We establish a version of a classical theorem of Pommerenke, which is a diameter version of the Gehring-Hayman inequality on Gromov hyperbolic domains of $\mathbb{R}^n$. Two applications are given. Firstly, we generalize Ostrowski's Faltensatz to qua

We study numerical conformal mappings of planar Jordan domains with boundaries consisting of finitely many circular arcs and compute the moduli of quadrilaterals for these domains. Experimental error estimates are provided and, when possible, compari
