Asymptotics for general connections at infinity [PDF]
, 2003 For a standard path of connections going to a generic point at infinity in the moduli space $M_{DR}$ of connections on a compact Riemann surface, we show that the Laplace transform of the family of monodromy matrices has an analytic continuation with ...

, 2008 We prove an asymptotically tight bound (asymptotic with respect to the number of polynomials for fixed degrees and number of variables) on the number of semi-algebraically connected components of the realizations of all realizable sign conditions of a ...

Engineering Reports, Volume 7, Issue 12, December 2025.Flow geometry. ABSTRACT This research formulates a two‐phase mathematical model to investigate the dynamics of a Maxwell dusty fluid across a linearly stretching surface embedded within a Darcy–Forchheimer porous medium, influenced by a magnetic field and varying thermal conductivity.

Engineering Reports, Volume 7, Issue 12, December 2025.A computational model for analyzing heat and mass transfer in MHD viscoelastic nanofluid flow with Brownian motion, thermal radiation and chemical reaction are developed in this work. The findings demonstrate how flow stability, heat transfer, and solute distribution are impacted by these significant physical effects.

The optimal homotopy asymptotic method with application to modified Kawahara equation [PDF]
Journal of the Association of Arab Universities for Basic and Applied Sciences, 2015 Abstract In this paper the optimal homotopy asymptotic method (OHAM) is introduced for obtaining the approximate solution of modified Kawahara equations. The OHAM results are compared with Variational Iteration Method (VIM), Homotopy Perturbation Method (HPM) and Exact solutions.

A Framework for the Solution of Tree‐Coupled Saddle‐Point Systems
Numerical Linear Algebra with Applications, Volume 32, Issue 6, December 2025.ABSTRACT We consider the solution of saddle‐point systems with a tree‐based block structure, introducing a parallelizable direct method for their solution. As our key contribution, we then propose several structure‐exploiting preconditioners to be used during applications of the GMRES algorithm and analyze their properties.

An optimal method for approximating the delay differential equations of noninteger order
Advances in Difference Equations, 2018 The main purpose of this paper is to use a method with a free parameter, named the optimal asymptotic homotopy method (OHAM), in order to obtain the solution of delay differential equations, delay partial differential equations, and a system of coupled ...

Battery Energy, Volume 4, Issue 5, September 2025.For a Casson flow which is under consideration here, its rheological equation is adopted with the assumptions of viscous dissipation properties of flow and all the constant properties. By Nakamura and Sawada, the model proposed, which is biviscosity, is implemented and is mostly used for the representation of Casson electrolytes in LIB.
