Construction of G^1 Hermite rational spline motion of degree six

2013-03-18 10:00-11:00 FAMNIT-SEMIN Karla Počkaj Construction of G^1 Hermite rational spline motion of degree six Geometric interpolation techniques have many advantages, such as automatically chosen parametrization, lower degree of interpolants and optimal approximation order. In this talk a geometric continuous…

Pentavalent arc-transitive bicirculants

2013-03-04 10:00-11:00 FAMNIT-SEMIN Ademir Hujdurović Pentavalent arc-transitive bicirculants A bicirculant is a graph admitting an automorphism with two cycles of equal length in its cycle decomposition. A graph is said to be arc-transitive if its automorphism group acts transitively on…

Extremal codes in distance-regular graphs with diameter 3

2013-02-25 10:00-11:00 FAMNIT-SEMIN Janoš Vidali (Univerza v Ljubljani, Fakulteta za računalništvo) Extremal codes in distance-regular graphs with diameter 3 We study $1$-codes in distance-regular graphs of diameter $3$ that achieve three different bounds. We show that the intersection array of…

Tutte polytope

2013-02-18 10:00-11:00 FAMNIT-SEMIN Matjaž Konvalinka (UL FMF, Ljubljana) Tutte polytope The Cayley polytope was defined recently as the convex hull of Cayley compositions, introduced by Cayley in 1857. In this talk, I will describe how we resolved Braun’s conjecture, which…
