Cover Story: The article derives novel degree sequence-based bounds on matching numbers, valid for any simple graph. The figure shows an application in number theory: the first 200 prime gaps are represented as node degrees in a simple graph and are generated via the degree-preserving growth (DPG) mechanism. The DPG builds an ever-growing graph sequence by joining a newly incoming node of a given degree (the next prime gap value) to the nodes of a randomly selected matching of proper size, then discarding the edges of the matching. The incoming nodes’ degrees constrain the size of the matching that can be selected, which, in turn, constrains the sizes of the future incoming degrees. It has previously been proven, however, that, for the prime gap sequence, this process can be continued indefinitely, if the Riemann hypothesis holds. View this paper
