Abstract
The spectrumsum of a graph is defined as the sum of the absolute values of its eigenvalues. The graphs with minimal spectrumsums in the class of connected bipartite graphs with exactly two vertexdisjoint cycles, in the class of connected bipartite graphs with exactly two vertexdisjoint cycles whose lengths are congruent with 2 modulo 4, and in the class of connected bipartite graphs with exactly two vertexdisjoint cycles one of which has length congruent with 2 modulo 4, are determined, respectively.
