Limitations on the superposition principle: superselection rules in non-relativistic quantum mechanics [PDF]
, 1998 The superposition principle is a very basic ingredient of quantum theory. What may come as a surprise to many students, and even to many practitioners of the quantum craft, is tha superposition has limitations imposed by certain requirements of the ...

On Convex Univalent Functions with Convex Univalent Derivatives
Rocky Mountain Journal of Mathematics, 2005 The authors studied the functions \[ \sum_{k=0}^{\infty}a_{k}\dfrac{(1+z)^k}{k!}, \] for \(a_{0}\geq a_{1}\geq...\geq 0\). They showed that these functions are either constant or convex univalent in the unit disk \(D\). The work is inspired by \textit{T. J.

THE SCHWARZIAN DERIVATIVES OF HARMONIC FUNCTIONS AND UNIVALENCE CONDITIONS
Проблемы анализа, 2017 In the paper we obtain some analogues of Nehari’s univalence conditions for sense-preserving functions that are harmonic in the unit disc D = {z ∈ C : |z| < 1}.

On the Theorem of Univalence on the Boundary
AxiomsWe give several generalizations of a known theorem from complex analysis, namely the univalence on the boundary theorem. Starting from a purely topological result (Theorems 1 and 11), we obtain univalence conditions for Sobolev mappings.

International Journal of Mathematics and Mathematical Sciences, 1996 The radius of univalence is found for the convolution f∗g of functions f∈S (normalized univalent functions) and g∈C (close-to-convex functions). A lower bound for the radius of univalence is also determined when f and g range over all of S.

Categorical structures for type theory in univalent foundations [PDF]
Logical Methods in Computer Science, 2018 In this paper, we analyze and compare three of the many algebraic structures that have been used for modeling dependent type theories: categories with families, split type-categories, and representable maps of presheaves. We study these in univalent type

Schwarzian Derivative Criteria for Valence of Analytic and Harmonic Mappings
, 2007 For analytic functions in the unit disk, general bounds on the Schwarzian derivative in terms of Nehari functions are shown to imply uniform local univalence and in some cases finite and bounded valence.

Factor Price Equalization : Geometrical Conditions [PDF]
, 1998 This paper presents a geometrical approach to the univalence problem for a system of cost functions. We present a natural (almost tautological) extension of a geometrical theorem due to McKenzie: our sufficient condition is related to the non ...

A uniform quantitative stiff stability estimate for BDF schemes [PDF]
Opuscula Mathematica, 2006 The concepts of stability regions, \(A\)- and \(A(\alpha)\)-stability - albeit based on scalar models - turned out to be essential for the identification of implicit methods suitable for the integration of stiff ODEs.

Sufficient Conditions for Univalence of an Integral Operator
Journal of Inequalities and Applications, 2008 In this paper we have introduced an integral general operator. For this general operator which is a generalization of more known integral operators we have demonstrated some univalence properties.
