MODULI SPACES OF RATIONAL WEIGHTED STABLE CURVES AND TROPICAL GEOMETRY
Forum of Mathematics, Sigma, 2016 We study moduli spaces of rational weighted stable tropical curves, and their connections with Hassett spaces. Given a vector $w$ of weights, the moduli ...

Genomic variation drives plant flavor diversification
Journal of Integrative Plant Biology, EarlyView.This review explains how genomic variation shapes plant flavor by altering the biosynthetic and regulatory pathways of key attributes like sweetness, acidity, bitterness, piquancy, astringency, and aroma. It also discusses how multi‐omics, AI‐assisted breeding, and gene editing can translate this knowledge into plants with improved flavor, nutrition ...

Toeplitz Operators on the Weighted Pluriharmonic Bergman Space with Radial Symbols
Abstract and Applied Analysis, 2011 We construct an operator R whose restriction onto weighted pluriharmonic Bergman Space bμ2(Bn) is an isometric isomorphism between bμ2(Bn) and l2#. Furthermore, using the operator R we prove that each Toeplitz operator Ta with radial symbols is unitary ...

Aggregate Market Power: Measurement, Drivers, and Macroeconomic Effects
Journal of Economic Surveys, EarlyView.ABSTRACT This survey reviews the macroeconomic literature on market power, focusing on its measurement, determinants, and macroeconomic effects. It synthesizes evidence from concentration ratios, business dynamism indicators, and markup/markdown estimates, documenting a distinct change in trends since the 1980s, especially in the United States ...

Korenblum’s Principle for Bergman Spaces with Radial Weights
Computational Methods and Function TheoryAbstract We show that the Korenblum maximum (domination) principle is valid for weighted Bergman spaces $$A^p_w$$ A w p with arbitrary (non-negative and

ON SOME EXTREMAL PROBLEMS IN CERTAIN HARMONIC FUNCTION SPACES OF SEVERAL VARIABLES RELATED TO MIXED NORM SPACES [PDF]
Проблемы анализа, 2013 In this paper we provide some (not new) estimates on distances from our two previous papers together with some new estimates. Namely some estimates on distances in spaces of harmonic functions in the unit ball and the upper half space are provided.

Second-Order Linear Differential Equations with Solutions in Analytic Function Spaces
Journal of Function Spaces, 2019 This research is concerned with second-order linear differential equation f′′+A(z)f=0, where A(z) is an analytic function in the unit disc. On the one hand, some sufficient conditions for the solutions to be in α-Bloch (little α-Bloch) space are found by

Detecting Favoritism in Public Procurement
The Journal of Industrial Economics, EarlyView.ABSTRACT Favoritism as a mode of corruption is a major concern in public procurement (PP) in many countries. We propose a regression discontinuity design (RDD) test arguing that the winning history of marginal winners and losers can be used to detect favoritism.

AxiomsThe single generalized weighted composition operator Du,ψn on various spaces of analytic functions has been investigated for decades, i.e., Du,ψnf=u·(f(n)∘ψ), where f∈H(D).

Discrete Dynamics in Nature and Society, 2008 We introduce an integral-type operator, denoted by Pφg, on the space of holomorphic functions on the unit ball B⊂ℂn, which is an extension of the product of composition and integral operators on the unit disk.
