Self-Commutators of Composition Operators with Monomial Symbols on the Dirichlet Space

open access: yesAbstract and Applied Analysis, 2011
Let 𝜑(𝑧)=𝑧𝑛,𝑧∈𝕌, for some positive integer 𝑛 and 𝐶𝜑 the composition operator on the Dirichlet space 𝒟 induced by 𝜑. In this paper, we completely determine the point spectrum, spectrum, essential spectrum, and essential norm of the operators 𝐶∗𝜑𝐶𝜑,𝐶𝜑𝐶∗𝜑 ...

A Game-Theoretic Analysis of Baccara Chemin de Fer

open access: yesGames, 2013
Assuming that cards are dealt with replacement from a single deck and that each of Player and Banker sees the total of his own two-card hand but not its composition, baccara is a 2 x 288 matrix game, which was solved by Kemeny and Snell in 1957. Assuming

Imaging of Biphoton States: Fundamentals and Applications

open access: yesAdvanced Functional Materials, EarlyView.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

WGO: a similarly encoded whale-goshawk optimization algorithm for uncertain cloud manufacturing service composition

open access: yesAutonomous Intelligent Systems
Service Composition and Optimization Selection (SCOS) is crucial in Cloud Manufacturing (CMfg), but the uncertainties in service states and working environments pose challenges for existing QoS-based methods.

Partition and composition matrices: two matrix analogues of set partitions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
This paper introduces two matrix analogues for set partitions; partition and composition matrices. These two analogues are the natural result of lifting the mapping between ascent sequences and integer matrices given in Dukes & Parviainen (2010).

The Mixed Blessings of Pragmatism. Jean-Baptiste Dumas and the (Al)chemical Quest for Metallic Transmutation

open access: yesSubstantia, 2023
There were at least three prerequisites for the transmutability of metals to become once again a scientifically acceptable subject of research from the 1810s: new hypotheses concerning the mutual reducibility of certain elements, such as those of ...

Thermally Activated Delayed Fluorescence in Phase‐Separated Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A supramolecular, phase‐separation driven strategy yields charge transfer (CT) complexes from alternating electron‐deficient pyromellitic diimide and electron‐rich 4,5‐dibromoveratrole. The resulting CT complexes self‐assemble into lamellar nanosheets with nanometer‐sized domains that exhibit thermally activated delayed fluorescence (TADF) at room ...

Weighted Differentiation Composition Operator from Logarithmic Bloch Spaces to Zygmund-Type Spaces

open access: yesAbstract and Applied Analysis, 2014
Let H(𝔻) denote the space of all holomorphic functions on the unit disk 𝔻 of ℂ, u∈H(𝔻) and let  n be a positive integer, φ a holomorphic self-map of 𝔻, and μ a weight.

The number of distinct part sizes of some multiplicity in compositions of an Integer. A probabilistic Analysis [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Random compositions of integers are used as theoretical models for many applications. The degree of distinctness of a composition is a natural and important parameter. A possible measure of distinctness is the number $X$ of distinct parts (or components).
