Optimal control on a metric graph for a damped linear fractional hyperbolic problem

open access: yesResults in Control and Optimization
The optimal control of fractional PDEs has been extensively studied in standard domains, but the existence and uniqueness of optimal controls in metric graphs, particularly for hyperbolic equations, remain less explored.

Nonoscillatory Central Schemes for Hyperbolic Systems of Conservation Laws in Three-Space Dimensions

open access: yesThe Scientific World Journal, 2013
We extend a family of high-resolution, semidiscrete central schemes for hyperbolic systems of conservation laws to three-space dimensions. Details of the schemes, their implementation, and properties are presented together with results from several ...

Conjugacy in normal subgroups of hyperbolic groups

open access: yes, 2012
Let N be a finitely generated normal subgroup of a Gromov hyperbolic group G. We establish criteria for N to have solvable conjugacy problem and be conjugacy separable in terms of the corresponding properties of G/N.

Hyperbolic approximation of the fourier transformed vlasov equation

open access: yesESAIM: Proceedings and Surveys, 2014
We construct an hyperbolic approximation of the Fourier transformed Vlasov equation in which the dependency on the spectral-velocity variable is removed. The model is constructed from the Vlasov equation after a Fourier transformation

On stability for symmetric hyperbolic systems, II

open access: yesJournal of Differential Equations, 1981
In a very wide spectrum of applications, the problem of stability plays a central role. There is a vast literature available in the field, but still the problem is solved only in special cases. The incompleteness of the literature is especially noticeable when the governing equations are partial differential equations.

Skew product cycles with rich dynamics: from totally non-hyperbolic dynamics to fully prevalent hyperbolicity

open access: yes, 2016
We introduce a two-parameter family of partially hyperbolic' skew products (G(a, t)) maps with one dimensional centre direction. In this family, the parameter a models the central dynamics and the parameter t the unfolding of cycles (that occurs for t ...

Inherent altermagnetism in minimal tight-binding models of regular hyperbolic lattices

open access: yesPhysical Review Research
Altermagnets are a novel class of magnetic systems characterized by their momentum-dependent spin splitting without net magnetization. In this work, we extend established Euclidean tight-binding models of altermagnets to regular hyperbolic lattices in ...

Modelling of Nonuniform RC Structures for Computer Aided Design

open access: yesActive and Passive Electronic Components, 1994
A simple model for nonuniform distributed RC structures is presented. The model consists of three passive elements only and can be used for modelling nonuniform distributed RC structures involving exponential, hyperbolic sine squared, hyperbolic cosine ...

Euclidean decompositions of hyperbolic manifolds and their duals [PDF]

open access: yes, 2007
Epstein and Penner constructed in [EP88] the Euclidean decomposition of a non-compact hyperbolic n-manifold of finite volume for a choice of cusps, n >= 2. The manifold is cut along geodesic hyperplanes into hyperbolic ideal convex polyhedra.

An Innovative Hybrid Scheme for Improving the Stability of Nonlinear Control Systems

open access: yesJournal of Mathematics
In this research, a hybrid method for designing stabilizing feedback control for nonlinear systems is provided. First of all, according to the hyperbolic functions, the nonlinear control systems has been estimated.
