Asymptotic stability of small solitons in the discrete nonlinear Schr¨odinger equation in one dimension
Small solitary wave one dimensional discrete nonlinear septic nonlinear power law equation
2014/12/25
Asymptotic stability of small solitons in one dimension is proved in the framework of a discrete nonlinear Schr¨odinger equation with septic and higher power-law nonlinearities and an external potenti...

Topics in Multivariate Time Series Analysis Statistical Control Dimension Reduction Visualization Their Business Applications
2014/10/28
Most business processes are, by nature, multivariate and autocorrelated. Highdimensionality is rooted in processes where more than one variable is considered simultaneously to provide a more comprehen...
From Fourier to Gegenbauer: Dimension walks on spheres
Fourier to Gegenbauer Dimension walks on spheres
2013/4/28
We show that the even- resp. odd-dimensional Schoenberg coefficients in Gegenbauer expansions of isotropic positive definite functions on the d-sphere can be expressed as linear combinations of Fourie...
Predictive Correlation Screening: Application to Two-stage Predictor Design in High Dimension
Predictive Correlation Screening Application Two-stage Predictor Design High Dimension
2013/4/27
We introduce a new approach to variable selection, called Predictive Correlation Screening, for predictor design. Predictive Correlation Screening (PCS) implements false positive control on the select...

Directional regression electroencephalography Kronecker en-velope sliced inverse regression sliced average variance estimate
2010/3/11
We consider dimension reduction for regression or classification
in which the predictors are matrix- or array-valued. This type of pre-
dictor arises when measurements are obtained for each combinat...

Suppose that X is a two-dimensional Brownian motion.
The trace X[O, I] contains a self-avoiding continuous path
whose Hausdorff dimension is equal to 2.

Hausdorff dimension theorems self-similar Markov processes
2009/9/22
Let X(t) (ts R,) be an u-self-similar Markov process
on Rd or Rd+. The Hausdorff dimension of the image, graph and zero
set of X(t) are obtained under certain mild conditions. Similar results
are a...
Box dimension of interpolations of self-similar processes with stationary increments
Fractal interpolation interpolation dimension box dimension self-similar process
2009/9/21
We prove that under a general condition interpolation
dimensions of H-sssi process converge in probabiIity to 2-H. The
result can be applied to a wide class of H-sssi processes which includes
fract...

Planar Brownian Motion Frontier Dimension Disconnection Exponents
2009/5/11
Let $B$ be a two dimensional Brownian motion and let the frontier of $B[0,1]$ be defined as the set of all points in $B[0,1]$ that are in the closure of the unbounded connected component of its comple...
Let $B(t)$ be a Brownian motion in $R^3$. A {it subpath} of the Brownian path $B[0,1]$ is a continuous curve $gamma(t)$, where $gamma[0,1] subseteq B[0,1]$ , $gamma(0) = B(0)$, and $gamma(1) = B(1)$. ...
Support of a Marcus equation in Dimension 1
Marcus equation pathwise representation support theorem
2009/5/4
The purpose of this note is to give a support theorem in the Skorohod space for a one-dimensional Marcus differential equation driven by a Lévy process, without any assumption on the latter. We also g...

2009/4/8
In Chen and Li (2004), large deviations were obtained for the spatial $L^p$ norms of products of independent Brownian local times and local times of random walks with finite second moment. The methods...
