Fourier and Cauchy-Stieltjes transforms of power laws including stable distributions
Fourier transform Cauchy-Stieltjes transform stable distribution non-commutative probability Diophantine approximation

2011/9/15
Abstract: The Pareto distribution is a basic probability distribution which shows power-law behaviour and has various kinds of applications. In this paper, we introduce a class of probability measures...
Abstract composition laws and their modulation spaces
Pseudodifferential operator Moyal algebra Weyl product modulation mapping modulation space

2011/9/13
Abstract: On classes of functions de?ned on R^2n we introduce abstract composition laws modelled after the pseudodifferential product of symbols. We attach to these composition laws modulation mapping...
On the existence of a time inhomogeneous skew Brownian motion and some related laws

Abstract: This article is devoted to the construction of a solution for the "skew inhomogeneous Brownian motion" equation, which first appear in a seminal paper by Sophie Weinryb (1983). We investigat...
Discrete conservation laws and port-Hamiltonian systems on graphs and complexes

Abstract: In this paper we present a unifying geometric framework for modeling various sorts of physical network dynamics as port-Hamiltonian systems. Basic idea is to associate with the incidence mat...
Riesz measures and Wishart laws associated to quadratic maps

Abstract: We introduce a natural definition of Riesz measures and Wishart laws associated to an $\Omega$-positive (virtual) quadratic map, where $\Omega \subset \real^n$ is a regular open convex cone....
Scaling laws prediction from a solvable model of turbulent thermal convection
Scaling laws solvable model turbulent thermal convection
<
2011/7/7
A solvable turbulent model is used to predict both the structure of the boundary layer and the scaling laws in thermal convection. The transport of heat depends on the interplay between the thermal, v...
The matrix Lax representation of the generalized Riemann equations and its conservation Laws

<
2011/7/5
It is shown that the generalized Riemann equation is equivalent with the
multicomponent generalization of the Hunter - Saxton equation. New matrix
and scalar Lax representation is presented for this...
Multiplicative zero-one laws and metric number theory
Zero-one laws metric Diophantine approximation
<
2011/1/18
We develop the classical theory of Diophantine approximation without assuming monotonicity or convexity. A complete ‘multiplicative’ zero-one law is established akin to the ‘simultaneous’ zero-one law...

2010/11/23
We propose new Kruzhkov type entropy conditions for one dimensional scalar conservation law with a discontinuous flux. We prove existence and uniqueness of the entropy admissible weak solution to the ...

In this paper we prove a new chain rule formula for the distributional derivative of the composite function $v(x)=B(x,u(x))$, where $u:]a,b[\to\R^d$ has bounded variation, $B(x,\cdot)$ is continuousl...

2010/11/18
We prove the $L^\infty(L^\infty)$-boundedness of a higher-order shock-capturing streamline-diffusion DG-method based on polynomials of degree $p\geq 0$ for general scalar conservation laws. The estim...
On a kind of Noether symmetries and conservation laws in k-cosymplectic field theory

2010/12/6
This paper is devoted to studying symmetries of certain kinds of k-cosymplectic Hamiltonian
systems in first-order classical field theories. Thus, we introduce a particular class of
symmetries and s...
Factorization systems induced by weak distributive laws

2010/11/29
We relate weak distributive laws in SetMat to strictly associative (but not strictly unital) pseudoalgebras of the 2-monad (−)2 on Cat. The corresponding orthogonal factorization systems are cha...
Selfdecomposable Laws Associated with Hyperbolic Functins

2010/12/8
t is shown that the hyperbolic functions can be associated with selfdecomposable distributions (in short: SD probability distributions or L´evy class L probability laws). Consequently, they admi...
A weak mixed distributive law (also called weak entwining structure [6]) in a 2-category consists of a monad and a comonad, together with a 2-cell relating them in a way which generalizes a mixed dist...
