(IOP PUBLISHING LTDBRISTOL, 2015)
Vertex-switching reconstruction and related problems
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAPrograma de Pós-Graduação em MatemáticaUFMG, 2019-08-28)
O objetivo deste trabalho é apresentar métodos de álgebra linear para a resolução de alguns problemas relacionados ao problema de reconstrução de grafos por vertex-switching de Stanley (1985). O Lema de ...
A four vertex theorem for strictly convex space curves
(Journal of Geometry, 2018)
The cohomology of the Grassmannian is a gln-module
(2019-01-01)
The integral singular cohomology ring of the Grassmann variety parametrizing r-dimensional subspaces in the n-dimensional complex vector space is naturally an irreducible representation of the Lie algebra (Formula presented.) ...
Type IIB superstring vertex operator from the -8 picture
(2022-01-01)
A new procedure was recently proposed for constructing massless Type IIB vertex operators in the pure spinor formalism. Instead of expressing these closed string vertex operators as left-right products of open string vertex ...
Polygonal approximation of digital planar curves through vertex betweenness
(ElsevierPhiladelphia, 2013-02)
Contour polygonal approximation is usually defined as a set of selected points, which describes a polygon and best represents the original contour. This paper presents a novel graph based approach to compute a polygonal ...
