Web2 days ago · Interestingly, we know that dual systolic graphs exist, but we do not yet know how to efficiently construct them. We, therefore, define a weaker notion of dual systolicity. We prove the same isoperimetric inequality for weakly dual systolic graphs, and at the same time provide an efficient construction of a family of graphs that are weakly dual ...
