Monotonicity conjecture for new KMP eigenvalues
Let be a hypergraph with non-negative weights. For every , let denote the smallest new eigenvalue of the Laplacian , meaning the smallest eigenvalue arising in the new invariant subspace at level . Monotonicity conjecture for new KMP eigenvalues.
The inequalities are supported by computer simulations and generalize the proved result for hypergraphs supported on subsets of size . The source gives no resolution in general.
