Emergence of a singularity for Toeplitz determinants and Painleve V [PDF]

open access: yes, 2011
We obtain asymptotic expansions for Toeplitz determinants corresponding to a family of symbols depending on a parameter $t$. For $t$ positive, the symbols are regular so that the determinants obey Szeg\H{o}'s strong limit theorem.

FIRST REPORT OF Meloidogyne incognita PARASITIZING Momordica charantia L. IN PERNAMBUCO, BRAZIL

open access: yesCiência Agrícola, 2020
Momordica charantia roots showing symptoms of root-knot disease were collected from vegetable gardens in the city of Recife, PE, Brazil. Through morphological and enzymatic characterization and molecular analysis of ITS and 28S rDNA regions, Meloidogyne ...

Identification of a lipolytic Trichoderma sp. and characterization of its extracellular lipase

open access: yesCeylon Journal of Science, 2023
Lipases are abundantly used in a wide range of industries. Currently, microbial lipases are the most popular source of industrial lipases, of which fungal lipases stand out due to their low cost of production, catalytic activity, and extracellular nature.

Monodromy dependence and connection formulae for isomonodromic tau functions [PDF]

open access: yes, 2018
We discuss an extension of the Jimbo-Miwa-Ueno differential 1-form to a form closed on the full space of extended monodromy data of systems of linear ordinary differential equations with rational coefficients. This extension is based on the results of M.

Molecular-genetic analysis of Malus sieversii – comparison of Dzungarian populations in situ and ex situ

open access: yesTurczaninowia, 2019
Malus sieversii (Ledeb.) M. Roem. is recognized as the ancestor of the cultivated apple tree. It has a valuable gene pool, and in the last decades, it becomes endangered in Kazakhstan.

Correlations in the impenetrable electron gas

open access: yes, 1998
We consider non-relativistic electrons in one dimension with infinitely strong repulsive delta function interaction. We calculate the long-time, large-distance asymptotics of field-field correlators in the gas phase.

The Widom-Dyson constant for the gap probability in random matrix theory [PDF]

open access: yes, 2006
In this paper we consider an asymptotic question in the theory of the Gaussian Unitary Ensemble of random matrices. In the bulk scaling limit, the probability that there are no eigenvalues in the interval (0,2s) is given by P_s=det(I-K_s), where K_s is ...
