2023/11/7
In this talk, we define a new class of differential fields called separably differentially closed fields and show their several characterizations by comparing them with differentially closed fields of...

Backstepping controller synthesis and characterizations of incremental stability
Backstepping controller synthesis characterizations of incremental stability Optimization and Control
2012/7/9
Incremental stability is a property of dynamical and control systems, requiring the uniform asymptotic stability of every trajectory, rather than that of an equilibrium point or a particular time-vary...
Convex dwell-time characterizations for uncertain linear impulsive systems
Impulsive systems dwell-time looped-functionals stability robustness
2012/5/9
New sufficient conditions for the characterization of dwell-times for linear impulsive systems are proposed and shown to coincide with continuous decrease conditions of a certain class of looped-funct...
Characterizations of distributions via order statistics with random exponential shifts
characterizations order statistics exponential distribution generalized logistic distribution
2011/9/19
Abstract: A class of probability distributions is characterized via equalities in law between two order statistics shifted by independent exponential variables. An explicit formula for the quintile fu...
Projective Hulls and Characterizations of Meromorphic Functions
Projective Hulls Maximum Principle Pluripotential Theory
2011/9/16
Abstract: We give conditions characterizing holomorphic and meromorphic functions in the unit disk of the complex plane in terms of certain weak forms of the maximum principle. Our work is directly in...

2011/9/13
Abstract: Let $\Omega$ be a strongly Lipschitz domain of $\mathbb{R}^n$, whose complement in $\mathbb{R}^n$ is unbounded. Let $L$ be a second order divergence form elliptic operator on $L^2 (\Omega)$ ...

2011/9/1
Abstract: Let $\mathcal{A}$ be an operator algebra on a Hilbert space. We say that an element $G\in {\mathcal{A}}$ is an all-derivable point of ${\mathcal{A}}$ if every derivable linear mapping $\phi$...

In this paper we have discusses -left, -right, -bi-, -quasi-, -interior and -ideals in -AG-groupoids and regular -AG...
On affine maps on non-compact convex sets and some characterizations of finite-dimensional solid ellipsoids
affine maps non-compact convex sets characterizations of finite-dimensional solid ellipsoids
2011/2/25
In recent studies, properties of the set of affine maps between two convex sets have been
investigated with intensive motivation from quantum physics, but in those preceding works
the underlying con...
Various characterizations of Besov-Dunkl spaces
Dunkl operators Dunkl transform Dunkl translation operators
2011/2/28
In this paper, different characterizations of the Besov-Dunkl spaces, previously considered in [1, 2, 3, 11], are given. We provide equivalence between these characterizations, using the Dunkl transla...
Characterizations of projective spaces and hyperquadrics
Characterizations of projective spaces hyperquadrics
2011/2/25
Projective spaces and hyperquadrics are the simplest projective algebraic varieties, and they can be characterized in many ways. The aim of this paper is to provide a new characterization of them in t...
Rigid characterizations of pseudoconvex domains

2011/3/1
We prove that an open set D in Cn is pseudoconvex if and only if for any z ∈ D the largest balanced domain centered at z and contained in D is pseudoconvex, and consider analogues of that characteriza...

2010/9/21
In this paper, we study the notion of intuitionistic fuzzy ideals of Γ–rings and study some of its properties.
