Jacob Holm was flipping through proofs from an October 2019 research paper he and colleague Eva Rotenberg—an associate professor in the department of applied mathematics and computer science at the ...

Area: discrete mathematics and graph theory with applications to biology and network science. Results on problems in extremal set theory, crossing numbers, problems related to degree sequences in ...

Extremal graph theory seeks to determine the maximum or minimum values of graph invariants—such as edge count, degree sequence or subgraph density—subject to the exclusion of particular configurations ...

The first handheld graphing calculator, the Casio fx-7000G, appeared in 1985. Since then, graphing calculators have become a common – and controversial – tool for learning mathematics. These devices ...

In 1957, the Soviet Union launched Sputnik, the first artificial satellite, into orbit, kicking off the space race during the Cold War. What do you notice when you compare the weather of 1978 with ...

Avi Wigderson and László Lovász won for their work developing complexity theory and graph theory, respectively, and for connecting the two fields. When Avi Wigderson and László Lovász began their ...

Graph labeling and colouring constitute a vibrant area of combinatorial mathematics concerned with the systematic assignment of discrete labels or colours to graph elements—typically vertices, edges ...

This premium teaching-resource bundle supports the Pearson Edexcel Year 2 A Level Pure Mathematics chapter on functions and graphs. It develops the key ideas of modulus functions, mappings, domain and ...
