Distribution of deformed Laplacian limit points
Elismar R. Oliveira, Jonas Szutkoski, VIlmar Trevisan
This paper investigates limit points of the deformed Laplacian matrix, which merges the Laplacian and signless Laplacian matrices of a graph through a quadractic one-parameter fami…

Functional Decomposition using Principal Subfields
Luiz E. Allem, Juliane Capaverde, Mark van Hoeij +1
Let be a univariate rational function. It is well known that any non-trivial decomposition , with , corresponds to a non-trivial subfield $K(f(t…

The Complexity of Computing all Subfields of an Algebraic Number Field
Jonas Szutkoski, Mark van Hoeij
For a finite separable field extension K/k, all subfields can be obtained by intersecting so-called principal subfields of K/k. In this work we present a way to quickly compute the…
