Metric basis and metric dimension has become an integral part of molecular topology and combinatorial chemistry. It has a lot of applications in pharmacy, chemistry, computer, and mathematical disciplines. Let \\(\\Phi =(V,E)\\) be a simple connected graph. A subset \\(F=\\{y_{1}, ...
ACartesian planeis a graph with one x-axis and one y-axis (that’s why it’s sometimes called an X Y graph). These two axes are perpendicular to each other. Theorigin(O) is in the exact center of the graph. Numbers to the right of the zero on the x-axis are positive; numbers ...
Complex numbers can be graphed, but use a different system to identify their coordinates that functions similarly to real number graphs. Learn how complex numbers are represented on complex axes and planes as a point on a graph. Unrelated Numbers Being a math guy, I was also pretty into my ...
Let S be a set of n points in general position in the plane. Together with S we are given a set of parity constraints, that is, every point of S is labeled either even or odd. A graph G on S satisfies the parity constraint of a point p ∈ S, if the

In this work, we directly reveal the in-plane and out-of-plane excitonic evolutions of 2D PTCDA (perylene-3,4,9,10-tetracarboxylic dianhydride) crystals grown on hexagonal BN (hBN) substrates in an unprecedented manner using polarized photoluminescence (PL) and absorption spectroscopies. The crysta...
We give an explicit calculation of the Wu invariants for immersions of a finite graph into the plane and classify all generic immersions of a graph into the plane up to regular homotopy by the Wu invariant. This result is a generalization of the fact that two plane curves are regularly hom...

Gary Miller has subsequently generalized my result to surfaces of arbitrary genus, so that there is now a graph isomorphism algorithm which is polynomial for any fixed genus.会议名称: Proceedings of the 12th Annual ACM Symposium on Theory of Computing, April 28-30, 1980, Los Angeles, California...
