Graph curvature and Laplacian operators form a vibrant area of research at the intersection of differential geometry and graph theory. The concept of graph curvature, inspired by classical Ricci ...
Carpathian Journal of Mathematics, Vol. 39, No. 2 (2023), pp. 371-382 (12 pages) The crossing number cr(G) of a graph G is the minimum number of edge crossings over all drawings of G in the plane. In ...
We can compare discrete and continuous data by looking at how water comes out of a tap. A dripping tap shows discrete data, because each individual drop can be counted. The data collected will simply ...
