When two quantities are in direct proportion, as one increases the other does too. We can display this relationship in a graph. Two quantities that are in direct proportion will always produce a ...

We develop a theory of graph C*-algebras using path groupoids and inverse semigroups. Row finiteness is not assumed so that the theory applies to graphs for which there are vertices emitting a ...

Control and inverse problems in wave equations and graphs constitute a dynamic field at the intersection of applied mathematics, engineering and physics. This area investigates how waves propagating ...
