Tropical Intersections and Rational Functions on Graphs
This write-up is concerned with the intersections of tropical curves and their relationship to rational functions on graphs. It is based on projects for Bernd Sturmfel’s 255 course in Fall 2011, Martin Olsson’s 256B course in Spring 2012, and work with Matt Baker. Sections 2 and 3 run through previous results on tropical intersections in the transverse and non-transverse cases, respectively. Se...
متن کاملDecomposing Envelopes of Rational Hypersurfaces
The envelope of a family of real, rational hypersurfaces is defined by an implicit equation in the parameter space. This equation can be decomposed into factors that are mapped to varieties of different dimension. The factorization can be found using solely gcd computations and polynomial divisions. The decomposition is used to derive some general results about envelopes, which also contribute ...
متن کاملDecomposing bent functions
In a recent paper [1], it is shown that the restrictions of bent functions to subspaces of codimension 1 and 2 are highly nonlinear. Here, we present an extensive study of the restrictions of bent functions to affine subspaces. We propose several methods which are mainly based on properties of the derivatives and of the dual of a given bent function. We solve an open problem due to Hou [2]. We ...
متن کاملDecomposing replicable functions
We describe an algorithm to decompose rational functions from which we determine the poset of groups fixing these functions.
متن کاملWall rational functions and Khrushchev’s formula for orthogonal rational functions
We prove that the Nevalinna-Pick algorithm provides different homeomorphisms between certain topological spaces of measures, analytic functions and sequences of complex numbers. This algorithm also yields a continued fraction expansion of every Schur function, whose approximants are identified. The approximants are quotients of rational functions which can be understood as the rational analogs ...
