On local linearization of control systems [PDF]
We consider the problem of topological linearization of smooth (C infinity or real analytic) control systems, i.e. of their local equivalence to a linear controllable system via point-wise transformations on the state and the control (static feedback ...

Background independent quantizations: the scalar field II [PDF]
We are concerned with the issue of quantization of a scalar field in a diffeomorphism invariant manner. We apply the method used in Loop Quantum Gravity. It relies on the specific choice of scalar field variables referred to as the polymer variables. The

New cw-expansive homeomorphisms of surfaces [PDF]
In this article we characterize monotone extensions of cw-expansive homeomorphisms of compact metric spaces. We study the topology of its quotient space in the case of a compact surface.

Groups of piecewise linear homeomorphisms of flows [PDF]
To every dynamical system$(X,\varphi )$over a totally disconnected compact space, we associate a left-orderable group$T(\varphi )$. It is defined as a group of homeomorphisms of the suspension of$(X,\varphi )$which preserve every orbit of the suspension flow and act by dyadic piecewise linear homeomorphisms in the flow direction.

Asymptotic Properties of -Expansive Homeomorphisms on a Metric -Space
We define and study the notions of positively and negatively -asymptotic points for a homeomorphism on a metric -space. We obtain necessary and sufficient conditions for two points to be positively/negatively -asymptotic.

In practical applications, stochastic effects are normally viewed as the major sources that lead to the system’s unwilling behaviours when modelling real neural systems. As such, the research on network models with stochastic effects is significant.

Linearization of a Contractive Homeomorphism [PDF]
Let X be a topological space and ϕ: X ⟶ X a continuous self-mapping of X. We say that ϕ is linearized in L by Φ if there exists a topological embedding μ: X ⟶ L of the space X into the linear topological vector space L such that for all x ϵ X, μ (ϕ (x)) = Φ (μ (x)), where ϕ is a continuous linear operator on L.

Hopf differentials and smoothing Sobolev homeomorphisms [PDF]
We prove that planar homeomorphisms can be approximated by diffeomorphisms in the Sobolev space $W^{1,2}$ and in the Royden algebra. As an application, we show that every discrete and open planar mapping with a holomorphic Hopf differential is harmonic ...

Piecewise linear homeomorphisms: the scalar case
The class of piecewise linear homeomorphisms (PLH) provides a convenient functional representation for many applications wherein an approximation to data is required that is invertible in closed form. In this paper we introduce the graph intersection (GI) algorithm for "learning" piecewise linear scalar functions in two settings: "approximation", where
