3D Lagrangian Modelling of Viscous and Inviscid incompressible Flow Using Conservative and Non-conservative Riemann Solvers and Density Filtering [PDF]

مجله مدل سازی در مهندسی, 2021
In this paper, 3D numerical lagrangian modelling of flow was performed using Weakly Compressible Smoothed Particle Hydrodynamic (WCSPH) method. Navier Stokes and Euler Equations were used to simulate viscous and inviscid fluid flow respectively.

Megamaps: Construction and Examples [PDF]

Discrete Mathematics & Theoretical Computer Science, 2001
We consider the usual model of hypermaps or, equivalently, bipartite maps, represented by pairs of permutations that act transitively on a set of edges E.

Spin(8,C)-Higgs pairs over a compact Riemann surface

Open Mathematics, 2023
Let XX be a compact Riemann surface of genus g≥2g\ge 2, GG be a semisimple complex Lie group and ρ:G→GL(V)\rho :G\to {\rm{GL}}\left(V) be a complex representation of GG.

An Affine Model of a Riemann Surface Associated to a Schwarz–Christoffel Mapping

Axioms, 2021
In this paper, we construct an affine model of a Riemann surface with a flat Riemannian metric associated to a Schwarz–Christoffel mapping of the upper half plane onto a rational triangle.

On triangular (D_{n})-actions on cyclic p-gonal Riemann surfaces [PDF]

Opuscula Mathematica, 2016
A compact Riemann surface \(X\) of genus \(g\gt 1\) which has a conformal automorphism \(\rho\) of prime order \(p\) such that the orbit space \(X/ \langle \rho \rangle \) is the Riemann sphere is called cyclic \(p\)-gonal.

Wrapped branes and punctured horizons

Journal of High Energy Physics, 2020
Large classes of AdSp supergravity backgrounds describing the IR dynamics of p-branes wrapped on a Riemann surface are determined by a solution to the Liouville equation.

Topological classification of conformal actions on p-hyperelliptic and (q,n)-gonal Riemann surfaces [PDF]

Opuscula Mathematica, 2009
A compact Riemann surface \(X\) of genus \(g \gt 1\) is said to be \(p\)-hyperelliptic if \(X\) admits a conformal involution \(\rho\) for which \(X / \rho\) has genus \(p\). A conformal automorphism \(\delta\) of prime order \(n\) such that \(X / \delta\

M2-branes on discs and multi-charged spindles

Journal of High Energy Physics, 2022
We study supersymmetric AdS2 × Y 9 solutions of 11d supergravity where Y 9 is an S7 fibration over a Riemann surface equipped with a metric of non-constant curvature.

Twisted Hilbert spaces of 3d supersymmetric gauge theories

Journal of High Energy Physics, 2018
We study aspects of 3d N=2 $$ \mathcal{N}=2 $$ supersymmetric gauge theories on the product of a line and a Riemann surface. Performing a topological twist along the Riemann surface leads to an effective supersymmetric quantum mechanics on the line.
