https://en.wikipedia.org/wiki/Fr%C3%A9chet%20surface | In mathematics, a Fréchet surface is an equivalence class of parametrized surfaces in a metric space. In other words, a Fréchet surface is a way of thinking about surfaces independently of how they are "written down" (parametrized). The concept is named after the French mathematician Maurice Fréchet.

https://en.wikipedia.org/wiki/Hermann%20Schubert |
Hermann Cäsar Hannibal Schubert (22 May 1848 – 20 July 1911) was a German mathematician.
Schubert was one of the leading developers of enumerative geometry, which considers those parts of algebraic geometry that involve a finite number of solutions. In 1874, Schubert won a prize for solving a question posed by Zeuth... |

https://en.wikipedia.org/wiki/Spectral%20gap | In mathematics, the spectral gap is the difference between the moduli of the two largest eigenvalues of a matrix or operator; alternately, it is sometimes taken as the smallest non-zero eigenvalue. Various theorems relate this difference to other properties of the system.

https://en.wikipedia.org/wiki/Riggatron | A Riggatron is a magnetic confinement fusion reactor design created by Robert W. Bussard in the late 1970s. It is a tokamak on the basis of its magnetic geometry, but some unconventional engineering choices were made. In particular, Riggatron used copper magnets positioned inside the lithium blanket, which was hoped to... |

https://en.wikipedia.org/wiki/Generalizations%20of%20Fibonacci%20numbers | In mathematics, the Fibonacci numbers form a sequence defined recursively by:
That is, after two starting values, each number is the sum of the two preceding numbers.
The Fibonacci sequence has been studied extensively and generalized in many ways, for example, by starting with other numbers than 0 and 1, by adding m... |
