Le souci métaphysique de l’infini dans la construction de la science classique

open access: yesCahiers François Viète, 2003
We cannot study the 17th century and in particular the first developments of classical science by simply applying our modern reading grids. Indeed, as we show in this article by focusing on the concept of infinity, it is important not to conceive of it ...

Mathematics of gravitational lensing: multiple imaging and magnification [PDF]

open access: yesGeneral Relativity and Gravitation, 2010
The mathematical theory of gravitational lensing has revealed many generic and global properties. Beginning with multiple imaging, we review Morse-theoretic image counting formulas and lower bound results, and complex-algebraic upper bounds in the case of single and multiple lens planes.

Geometric Analysis of Medallion Pattern in Safavid Period Carpets [PDF]

open access: yesنگره, 2023
Carpets with Medallion patterns are a wide and unique collection of Iranian carpets that received a lot of attention in the Safavid period. Since these carpets are among the most important Iranian carpets, it is necessary to analyze them from different ...

A Mathematical Analysis of Multiple-Target Selex

open access: yesBulletin of Mathematical Biology, 2010
SELEX (Systematic Evolution of Ligands by Exponential Enrichment) is a procedure by which a mixture of nucleic acids can be fractionated with the goal of identifying those with specific biochemical activities. One combines the mixture with a specific target molecule and then separates the target-NA complex from the resulting reactions.

Computer research of the holomorphic dynamics of exponential and linear-exponential maps [PDF]

open access: yesКомпьютерные исследования и моделирование, 2018
The work belongs to the direction of experimental mathematics, which investigates the properties of mathematical objects by the computing facilities of a computer. The base is an exponential map, its topological properties (Cantor's bouquets) differ from

An Optimal Derivative-Free Ostrowski’s Scheme for Multiple Roots of Nonlinear Equations

open access: yesMathematics, 2020
Finding higher-order optimal derivative-free methods for multiple roots (m≥2) of nonlinear expressions is one of the most fascinating and difficult problems in the area of numerical analysis and Computational mathematics.

Fermionic one-loop amplitudes of the RNS superstring

open access: yesJournal of High Energy Physics, 2018
We investigate massless n-point one-loop amplitudes of the open RNS superstring with two external fermions and determine their worldsheet integrands.

A Combinatorial Approach to Multiplicity-Free Richardson Subvarieties of the Grassmannian [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
We consider Buch's rule for K-theory of the Grassmannian, in the Schur multiplicity-free cases classified by Stembridge. Using a result of Knutson, one sees that Buch's coefficients are related to Möbius inversion. We give a direct combinatorial proof of
