In mathematics, a geometric progression is a sequence of numbers in which each term after the first is found by multiplying the previous one by a fixed non-zero number. In mathematics, a geometric ...

Several papers have investigated sequences which have no k-term arithmetic progressions, finding bounds on their density and looking at sequences generated by greedy algorithms. Rankin in 1960 ...

Symplectic geometry is a relatively new field with implications for much of modern mathematics. Here’s what it’s all about. In the early 1800s, William Rowan Hamilton discovered a new kind of ...
