A new geometric °ow with rotational invariance
System of hyperbolic-parabolic equations rotational invariance global smooth solution time-asymptotic behavior hypersurface
2018/4/19
In this paper we introduce a new geometric flow with rotational invariance and prove that, under this kind of flow, an arbitrary smooth closed contractible hypersurface in the Euclidean space Rn+1 (n...
Limit-circle invariance of non-symmetric discrete Hamiltonian systems
difference operator deficiency index non-symmetric
2011/10/12
In this paper, we first give the related important Lemmas, and after discusses the non-symmetric discrete Hamiltonian system, and obtain the limit-circle invariance theorem. The main results contain c...
An Invariance Principle for the Tagged Particle Process in Continuum with Singular Interaction Potential
Diffusion processes interacting continuous particle systems random environment invariance principles
2011/9/1
Abstract: We consider the dynamics of a tagged particle in an infinite particle environment moving according to a stochastic gradient dynamics. For singular interaction potentials this tagged particle...
Controller Synthesis for Robust Invariance of Polynomial Dynamical Systems using Linear Programming
Controller Synthesis Robust Invariance Polynomial Dynamical Systems Linear Programming
2011/8/30
Abstract: In this paper, we consider a control synthesis problem for a class of polynomial dynamical systems subject to bounded disturbances and with input constraints. More precisely, we aim at synth...
Search for conformal invariance incompressible two-dimensional turbulence
two-dimensional turbulence conformal invarianc incompressible SLE
2011/7/5
We present a search for conformal invariance in vorticity isolines of two-dimensional compressible
turbulence. The vorticity is measured by tracking the motion of particles that float at the surface ...
Spectral Invariance of Besov-Bessel Subalgebras
Banach algebra matrix algebra Besov spaces Bessel potential spaces
2011/2/21
Using principles of the theory of smoothness spaces we give systematic constructions of scales of inverse-closed subalgebras of a given Banach algebra with the action of a d-parameter automorphism gro...
Invariance property of Morse homology on noncompact manifolds
Invariance property of Morse homology noncompact manifolds
2011/2/28
In this article, we focus on the invariance property of Morse homology on noncompact manifolds. We expect to apply outcomes of this article to several types of Floer homology, thus we define Morse hom...
Geometric invariance of mass-like asymptotic invariants
Geometric invariance mass-like asymptotic invariants
2011/2/22
We study coordinate-invariance of some asymptotic invariants such as the ADM mass or the
Chruściel-Herzlich momentum, given by an integral over a “boundary at infinity”. When changing the coordi...
Universal regular autonomous asynchronous systems: omega-limit sets, invariance and basins of attraction
asynchronous system limit set invariance basin of attraction
2011/3/4
The asynchronous systems are the non-deterministic real time-binary models of the asynchronous circuits from electrical engi-neering.
Conformal Invariance in Inverse Turbulent Cascades
Conformal Invariance Inverse Turbulent Cascades
2010/12/28
We study statistical properties of turbulent inverse cascades in a class of nonlinear models describ-ing a scalar field transported by a two-dimensional incompressible flow. The class is characterized...
We study in this paper certain properties of the responses of dynamical systems to external inputs. Our results are purely mathematical and thus of wide applicability, but our motivation arises from m...
A strong invariance principle for nonconventional sums
strong approximations limit theorems martingale approximation
2011/1/21
In [12] we obtained a functional central limit theorem (known also as a weak invariance principle) for sums of the form P[Nt] n=1 FX(n),X(2n), ...,X(kn),X(qk+1(n)),X(qk+2(n)),
Experimental evidence of conformal invariance in soap film turbulent flows
Experimental evidence of conformal invariance soap film turbulent flows
2011/3/2
We present experimental evidence of statistical conformal invariance in isocontours of fluid thickness in experiments of two-dimensional turbulence using soap films. A Schlieren technique is used to v...
Homotopy invariance for homology of linear groups: reductions and the rank two case
linear groups the rank two case
2010/11/24
We discuss the problem of homotopy invariance for homology of linear groups. Some reductions we are able to make show that homotopy invariance for linear groups follows from contractibility of a cert...
We show that some more results from the literature are particular cases of the so-called "invariance under twisting" for twisted tensor products of algebras, for instance a result of Beattie-Chen-Zhan...
