Maximizing subgraph counts in regular graphs
Gabor Lippner, Arturo Ortiz San Miguel
Given a graph , we investigate the -regular graphs with the highest -density. We reframe the problem as a continuous optimization problem on the eigenvalues of by…
Any fully graphic region of degree sequences can be sampled rapidly
Péter L. Erdős, Gábor Lippner, Na'ama Nevo +1
Let and be positive integers with Let $\mD=\dds{n}Σ{c_1}{c_2}$ denote the set of all degree sequences of length with the eve…
Pretty good fractional revival via magnetic fields: theory and examples
Whitney Drazen, Mark Kempton, Gabor Lippner
We develop the theory of pretty good quantum fractional revival in arbitrary sized subsets of a graph, including the theory for fractional cospectrality of subsets of arbitrary siz…
Approximate quantum fractional revival in paths and cycles
Ada Chan, Whitney Drazen, Or Eisenberg +2
We initiate the study of approximate quantum fractional revival in graphs, a generalization of pretty good quantum state transfer in graphs. We give a complete characterization of…
Fundamentals of fractional revival in graphs
Ada Chan, Gabriel Coutinho, Whitney Drazen +6
We develop a general spectral framework to analyze quantum fractional revival in quantum spin networks. In particular, we introduce generalizations of the notions of cospectral and…
Large scale Ricci curvature on graphs
Mark Kempton, Gabor Lippner, Florentin Munch
We define a hybrid between Ollvier and Bakry Emery curvature on graphs with dependence on a variable neighborhood. The hexagonal lattice is non-negatively curved under this new cur…
