In particular, the colouring of planar graphs—those which can be depicted on a plane without edge intersections—has attracted sustained attention due to its combinatorial complexity and ...

Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware-related errors may in fact be due ...

In this paper, a graph-theory-based approach for representing planar mechanisms is presented, the Santiago Portilla method (SPM). From the corresponding adjacency matrix, SPM generates an extended ...

Few things in life are more predictable than the chances of an incumbent member of the U.S. House of Representatives winning reelection. With wide name recognition, and usually an insurmountable ...

Learn about and revise ratio, proportion and rates of change with this BBC Bitesize GCSE Maths Edexcel study guide.

This is the first book to comprehensively cover chromatic polynomials of graphs. It includes most of the known results and unsolved problems in the area of chromatic polynomials. Dividing the book ...

aims to advance and promote the theory and applications of discrete mathematics, encouraging contributions from graph theory, combinatorics, and discrete optimization.
