TOPOLOGICAL CONDITIONS FOR SOLVA ILITY OF PSEUDO-TEARING SUBNETWORK

摘要

The problem for the solvability of pseudo-tearing subnetwork is one of the essentialinvestigations of network theory.The results presented would be not only mathematical conditionsbut also topological conditions for subnetwork solvability.These conditions are necessary andalmost sufficient.It should guide one intuitively to the design of accessible nodes.
