We investigate how the inverse degree index of graphs depends on their cyclomatic number. In particular, we provide sharp lower bounds on the inverse degree index over all graphs on a given number of ...

Learn how proportional relationships look on a graph, understand proportionality using worked examples, and for Higher tier, revise algebraic proportion.

Control and inverse problems in wave equations and graphs constitute a dynamic field at the intersection of applied mathematics, engineering and physics.
