In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...
On January 8, three mathematicians posted a proof of a nearly 60-year-old problem in combinatorics called Ringel's conjecture. Roughly speaking, it predicts that graphs — Tinkertoy-like constructions ...
Mathematicians have proved that copies of smaller graphs can always be used to perfectly cover larger ones. On January 8, three mathematicians posted a proof of a nearly 60-year-old problem in ...
