Wei, Dongming; Zhang, Zhenbu
(Electronic journal of differential equations, 2001)
In this work, we compare a parabolic equation with an elliptic
equation both of which are used in modeling temperature profile of a powerlaw
polymer
ow in a semi-infinite straight pipe with circular cross section.
We ...

Discovery of (strong) association rules, or implications, is an important
task in data management, and it nds application in arti cial intelligence,
data mining and the semantic web. We introduce a novel approach
for ...

(Nazarbayev University School of Science and Technology, 2019-05-29)
Many problems in theoretical physics are expressed in the form of Hamiltonian systems. Among these the first to be extensively studied were low-dimensional, possessing as few as two (or three) degrees of freedom. In the ...

It is known that hyperbolic dynamical systems admit a unique invariant probability measure with maximal entropy. We prove an effective version of this statement and use it to estimate an upper bound for Hausdorff dimension ...

(arXiv, 2018-04)
We examine the role of long–range interactions on the dynamical and statistical properties of two
1D lattices with on–site potentials that are known to support discrete breathers: the Klein–Gordon
(KG) lattice which ...

For a class C of finite lattices, the question arises whether any
lattice in C can be embedded into some atomistic, biatomic lattice in C. We
provide answers to the question above for C being, respectively,
— The class ...

We study the relation between measure theoretic entropy and escape of mass for the case of a singular diagonal flow on the moduli space of three-dimensional unimodular lattices

Let G be a connected semisimple Lie group of real rank 1 with finite center, let be a non-uniform lattice in G and a any diagonalizable element in G. We investigate the relation between the metric entropy of a acting ...

We show the abundance of Exceptional Points in the generic asymmetric configuration of two
coupled diode lasers, under nonzero optical detuning and differential pumping. We pinpoint the
location of these points with ...

In this paper we study the dimension of a family of sets arising in open dynamics. We use exponential mixing results for diagonalizable ows in compact homogeneous spaces X to show that the Hausdorff dimension of set of ...

(Applied Mathematical Sciences, 2013)
This paper is concerned with the existence of equilibrium states of a thin-walled hollow
elasto-plastic cylinders fully or partially submerged in a fluid. This problem serves as a
model for many problems with engineering ...

(Society for Industrial and Applied Mathematics. SIAM Journal on Numerical Analysis, 1992-04)
A quasilinear parabolic problem is studied. By using the method of lines, the existence and uniqueness of a solution to the initial boundary value problem with sufficiently smooth initial conditions are shown. Also given ...

In this work, we are going to reconstruct parameters of a discrete dynamical system
with a hidden layer, given by a quadruple of matrices (𝐴,𝐵,𝐶,𝐷), from system’s past behaviour. First, we reproduced experimentally ...

(The 4-th International Conference on Computer Processing of Turkic Languages “TurkLang 2016”, 2016)
Sentence alignment is the final step in building parallel corpora, which arguably has the greatest impact on the quality of a resulting corpus and the accuracy of machine translation systems that use it for training. ...

(SIAM Journal on Matrix Analysis and Applications, 2015)
A stable algorithm to compute the roots of polynomials is presented. The roots are found by computing the eigenvalues of the associated companion matrix by Francis's implicitly shifted QR algorithm. A companion matrix is ...

(arXiv, 2016-11-30)
In the last decade matrix polynomials have been investigated with the primary focus on adequate linearizations and good scaling techniques for computing their eigenvalues. In this article we propose a new backward stable ...
