Fusion Category Symmetry I: Anomaly In-Flow and Gapped Phases

We describe how to "ungauge" the fusion category symmetry in these boundary conditions and separate the symmetry-preserving phases from the symmetry-breaking ones. Expand abstract.

Existence of contacts for the motion of a rigid body into a viscous incompressible fluid with the Tresca boundary conditions

At the boundary of the fluid domain, we use the Tresca boundary conditions, that permit the fluid to slip tangentially on the boundary under some conditions on the stress tensor. Expand abstract.

Experimental boundary conditions of reinstatement induced return of fear in humans: Is reinstatement in humans what we think it is?

In sum, our results speak against the number of reinstatement USs as a potential boundary condition in experimentally-induced return of fear in humans and may challenge what we think we know about the reinstatement phenomenon in humans and call for a critical reconsideration of paradigms as well as mechanisms that may...

Artificial boundary method for the solution of pricing European options under the Heston model

Numerical experiments show that the proposed ABCs are able to improve the accuracy of the results and have a significant advantage over the widely-used boundary conditions by Heston in the original paper (Heston, 1993). Expand abstract.

Extension and comparison of techniques to enforce boundary conditions in Finite Volume POD-Galerkin reduced order models for fluid dynamic problems

A Finite-Volume based POD-Galerkin reduced order model is developed for fluid dynamic problems where the (time-dependent) boundary conditions are controlled using two different boundary control strategies: the control function method, whose aim is to obtain homogeneous basis functions for the reduced basis space and...

Lp-strong solution to fluid-rigid body interaction system with Navier slip boundary condition

We consider a fluid-rigid body interaction problem in $R^3$ and we are focusing on developing an $L^p$-theory for strong solutions of the coupled system, for both Newtonian and non-Newtonian fluids with the moving rigid body. Expand abstract.

Sufficient Stability Conditions for Time-varying Networks of Telegrapher's Equations or Difference Delay Equations

We give a sufficient condition for exponential stability of a network of lossless telegrapher's equations, coupled by linear time-varying boundary conditions. Expand abstract.

Global existence, smooth and stabilization in a three-dimensional Keller-Segel-Navier-Stokes system with rotational flux

We consider the spatially $3$-D version of the following Keller-Segel-Navier-Stokes system with rotational flux $$\left\{\begin{array}{l} n_t+u\cdot\nabla n=\Delta n-\nabla\cdot(nS(x,n,c)\nabla c),\quad x\in \Omega, t>0, c_t+u\cdot\nabla c=\Delta c-c+n,\quad x\in \Omega, t>0,\\ u_t+\kappa(u \cdot \nabla)u+\nabla P=\Delta u+n\nabla \phi,\quad x\in...

Absorbing Boundary Condition as Limiting Case of Imaginary Potentials

Imaginary potentials such as $V(x)=-iv 1_\Omega(x)$ (with $v>0$ a constant, $\Omega$ a subset of 3-space, and $1_\Omega$ its characteristic function) have been used in quantum mechanics as models of a detector. Expand abstract.

Diffusion Maps for Embedded Manifolds with Boundary with Applications to PDEs

Finally, using this estimated distance, we illustrate how to impose Dirichlet, Neumann, and mixed boundary conditions for some common PDEs based on the Laplacian. Expand abstract.
