Stabilization in relation to wavenumber in HDG methods
, 2015 Simulation of wave propagation through complex media relies on proper understanding of the properties of numerical methods when the wavenumber is real and complex.

Fixed-Parameter Complexity of Minimum Profile Problems
Algorithmica, 2006 Let $G=(V,E)$ be a graph. An ordering of $G$ is a bijection $ : V\dom \{1,2,..., |V|\}.$ For a vertex $v$ in $G$, its closed neighborhood is $N[v]=\{u\in V: uv\in E\}\cup \{v\}.$ The profile of an ordering $ $ of $G$ is $\prf_ (G)=\sum_{v\in V}( (v)-\min\{ (u): u\in N[v]\}).$ The profile $\prf(G)$ of $G$ is the minimum of $\prf_ (G)$ over all ...

Evidence for complex order parameter in La_{1.83}Sr_{0.17}CuO_4
, 2006 The in-plane magnetic field penetration depth (\lambda_{ab}) in single-crystal La_{1.83}Sr_{0.17}CuO_4 was investigated by means of the muon-spin rotation (\muSR) technique.

Modeling Smectic Layers in Confined Geometries: Order Parameter and Defects
, 2014 We identify problems with the standard complex order parameter formalism for smectic-A (SmA) liquid crystals, and discuss possible alternative descriptions of smectic order.

Information Geometry of Complex Hamiltonians and Exceptional Points
, 2013 Information geometry provides a tool to systematically investigate the parameter sensitivity of the state of a system. If a physical system is described by a linear combination of eigenstates of a complex (that is, non-Hermitian) Hamiltonian, then there ...

Homological Domination in Large Random Simplicial Complexes
, 2015 In this paper we state the homological domination principle for random multi-parameter simplicial complexes, claiming that the Betti number in one specific dimension (which is explicitly determined by the probability multi-parameter) significantly ...
