Asymptotic Expansion for a Periodic Boundary Condition

open access: yesJournal of Differential Equations, 1995
The authors introduce an approximation to flow problems in porous media when the boundary of the flow domain is partially covered by fluid. If the domain is \(\Omega= (0, \pi)\times (0, \pi)\) with a typical point \((x, y)\), they write \(\alpha\) and \(\gamma\) for the subsets of \(\partial\Omega\) on which \(y= 0\) and \(y= \pi\), respectively, and \(

Solvability of a fourth-order boundary value problem with periodic boundary conditions II

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
Let f:[0,1]×R4→R be a function satisfying Caratheodory's conditions and e(x)∈L1[0,1]. This paper is concerned with the solvability of the fourth-order fully quasilinear boundary value problem d4udx4+f(x,u(x),u′(x),u″(x),u‴(x))=e(x ...

Simplified Transfer Matrix Approach in the Two-Dimensional Ising Model with Various Boundary Conditions

open access: yes, 2002
A recent simplified transfer matrix solution of the two-dimensional Ising model on a square lattice with periodic boundary conditions is generalized to periodic-antiperiodic, antiperiodic-periodic and antiperiodic-antiperiodic boundary conditions.

Homoclinic snaking in bounded domains [PDF]

open access: yes, 2009
Homoclinic snaking is a term used to describe the back and forth oscillation of a branch of time-independent spatially localized states in a bistable, spatially reversible system as the localized structure grows in length by repeatedly adding rolls on ...

Thermal Convection in a Heated-Block Duct with Periodic Boundary Conditions by Element-by-Element Treatment

open access: yesInventions, 2023
The periodic nature of stream-wise flow occurs in a cooling channel so frequently due to the multiple heat sources in electronic equipment, demanding the creation of an effective technique to improve the heat-cooling convection.

Exact partition functions of the Ising model on MxN planar lattices with periodic-aperiodic boundary conditions

open access: yes, 2002
The Grassmann path integral approach is used to calculate exact partition functions of the Ising model on MxN square (sq), plane triangular (pt) and honeycomb (hc) lattices with periodic-periodic (pp), periodic-antiperiodic (pa), antiperiodic-periodic ...

Bistability in the Complex Ginzburg-Landau Equation with Drift [PDF]

open access: yes, 2009
Properties of the complex Ginzburg-Landau equation with drift are studied focusing on the Benjamin-Feir stable regime. On a finite interval with Neumann boundary conditions the equation exhibits bistability between a spatially uniform time-periodic state
