A nonzero integral flow f is conformally decomposable if $$f=f_1+f_2$$ , where $$f_1,f_2$$ are nonzero integral flows, both are nonnegative or both are nonpositive. Conformally indecomposable flows on ordinary graphs are simply graph circuit flows. H

The subtree number index of a graph, defined as the number of subtrees, attracts much attention recently. Finding a proper algorithm to compute this index is an important but difficult problem for a general graph. Even for unicyclic and bicyclic grap

Hartsfield and Ringel constructed orientable quadrangular embeddings of the complete graph $K_n$ for $n\equiv 5 \pmod 8$, and nonorientable ones for $n \ge 9$ and $n\equiv 1 \pmod 4$. These provide minimal quadrangulations of their underlying surface

We study tension–flows ( f , g ) on a graph G (where f is a tension and g is a flow) of the following types: nowhere-zero, product-zero everywhere, and complementary. Counting the number of tension–flows of the three types over modulo integer pai
