Counting invertible Schr\"odinger Operators over Finite Fields for Trees, Cycles and Complete Graphs
Résumé
We count invertible Schr\"odinger operators (perturbations by diagonal
matrices of the adjacency matrix) over finite fields
for trees, cycles and complete graphs.
This is achieved for trees through the definition and use of
local invariants (algebraic constructions of perhaps
independent interest).
Cycles and complete graphs are treated by ad hoc methods.
