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…
2012-10-15 10:00-11:00 FAMNIT-SEMIN Dr. Pim van ‘t Hof (University of Bergen, Norway) Obtaining Planarity by Contracting Few Edges The contraction of an edge uv in a graph G is the operation that deletes u and v from G, and replaces…
2013-03-11 10:00-11:00 FAMNIT-SEMIN Marcin Anholcer On Some Surprising Application of Graphs in Decision Making: Pairwise Comparisons In many multiple criteria decision making problems (in particular in the case of group expert decisions) the Pairwise Comparison Matrices (PCM) are used. In…
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…
