A model for n-dimensional boundary topology
Solid Modeling and Applications, 1993 The principle of representing a solid object by the structure of its boundary elements is a special case of describing an n-dimensional object by its (n-1)-dimensional bounding surface. By analogy to 2and 3-dimensional objects, a model representation for

BOUNDARY AND EXTERIOR OF A MULTISET TOPOLOGY
Journal of New Theory, 2016 − The concepts of exterior and boundary in multiset topological space are introduced. Wefurther established few relationships between the concepts of boundary, closure, exterior and interiorof an M - set.

An Inverse Problem for Quantum Trees with Delta-Prime Vertex Conditions
Vibration, 2020 In this paper, we consider a non-standard dynamical inverse problem for the wave equation on a metric tree graph. We assume that the so-called delta-prime matching conditions are satisfied at the internal vertices of the graph.

Topological divisors of zero and Shilov boundary
Topology and its Applications, 2006 AbstractLet L be a field complete for a non-trivial ultrametric absolute value and let (A,‖⋅‖) be a commutative normed L-algebra with unity whose spectral semi-norm is ‖⋅‖si. Let Mult(A,‖⋅‖) be the set of continuous multiplicative semi-norms of A, let S be the Shilov boundary for (A,‖⋅‖si) and let ψ∈Mult(A,‖⋅‖si). Then ψ belongs to S if and only if for

Introduction of a boundary in topological field theories [PDF]
Physical Review D, 2014 We study the consequences of the presence of a boundary in topological field theories in various dimensions. We characterize, univocally and on very general grounds, the field content and the symmetries of the actions which live on the boundary. We then show that these actions are covariant, despite appearances.

Thermoelectric performance of topological boundary modes [PDF]
Physical Review B, 2018 We investigate quantum transport and thermoelectrical properties of a finite-size Su-Schrieffer-Heeger model, a paradigmatic model for a one-dimensional topological insulator, which displays topologically protected edge states. By coupling the model to two fermionic reservoirs at its ends, we can explore the non-equilibrium dynamics of the system ...

Topology Optimization With Selective Problem Setups
IEEE Access, 2019 Topology optimization has demonstrated its power in structural design under a variety of physical disciplines. Generally, a topology optimization problem is formulated with clearly-defined problem setup.
