Researchers thought that they were five years away from solving a math riddle from the 1980's. In reality, and without knowing, they had nearly cracked the problem and had just given away much of the ...

Control and inverse problems in wave equations and graphs constitute a dynamic field at the intersection of applied mathematics, engineering and physics. This area investigates how waves propagating ...

University of California (UC) San Diego mathematicians Jacques Verstraete and Sam Mattheus have solved a puzzling Ramsey theory problem that's had little progress since the great Paul Erdös made some ...
