https://en.wikipedia.org/wiki/Semisimple%20Lie%20algebra | In mathematics, a Lie algebra is semisimple if it is a direct sum of simple Lie algebras. (A simple Lie algebra is a non-abelian Lie algebra without any non-zero proper ideals).
Throughout the article, unless otherwise stated, a Lie algebra is a finite-dimensional Lie algebra over a field of characteristic 0. For such... |

https://en.wikipedia.org/wiki/Andrew%20Appel | Andrew Wilson Appel (born 1960) is the Eugene Higgins Professor of computer science at Princeton University. He is especially well-known because of his compiler books, the Modern Compiler Implementation in ML () series, as well as Compiling With Continuations (). He is also a major contributor to the Standard ML of New... |
https://en.wikipedia.org/wiki/Corecursion | In computer science, corecursion is a type of operation that is dual to recursion. Whereas recursion works analytically, starting on data further from a base case and breaking it down into smaller data and repeating until one reaches a base case, corecursion works synthetically, starting from a base case and building i... |
https://en.wikipedia.org/wiki/Infinite-dimensional%20holomorphy | In mathematics, infinite-dimensional holomorphy is a branch of functional analysis. It is concerned with generalizations of the concept of holomorphic function to functions defined and taking values in complex Banach spaces (or Fréchet spaces more generally), typically of infinite dimension. It is one aspect of nonline... |
https://en.wikipedia.org/wiki/Oversampling | In signal processing, oversampling is the process of sampling a signal at a sampling frequency significantly higher than the Nyquist rate. Theoretically, a bandwidth-limited signal can be perfectly reconstructed if sampled at the Nyquist rate or above it. The Nyquist rate is defined as twice the bandwidth of the signal... |

https://en.wikipedia.org/wiki/Portable%20hole | In various works of speculative fiction, a portable hole is a two-dimensional device that can be used to contravene the laws of physics by creating a passage through a solid surface, through which characters can move.
Notable uses
The 1955 Looney Tunes cartoon, The Hole Idea, presents a fictional account in which Cal... |

https://en.wikipedia.org/wiki/Engel%27s%20theorem | In representation theory, a branch of mathematics, Engel's theorem states that a finite-dimensional Lie algebra is a nilpotent Lie algebra if and only if for each , the adjoint map
given by , is a nilpotent endomorphism on ; i.e., for some k. It is a consequence of the theorem, also called Engel's theorem, which say... |
https://en.wikipedia.org/wiki/Artin%E2%80%93Mazur%20zeta%20function | In mathematics, the Artin–Mazur zeta function, named after Michael Artin and Barry Mazur, is a function that is used for studying the iterated functions that occur in dynamical systems and fractals.
It is defined from a given function as the formal power series
where is the set of fixed points of the th iterate of ... |
https://en.wikipedia.org/wiki/Ihara%20zeta%20function | In mathematics, the Ihara zeta function is a zeta function associated with a finite graph. It closely resembles the Selberg zeta function, and is used to relate closed walks to the spectrum of the adjacency matrix. The Ihara zeta function was first defined by Yasutaka Ihara in the 1960s in the context of discrete subgr... |
https://en.wikipedia.org/wiki/Lerch%20zeta%20function | In mathematics, the Lerch zeta function, sometimes called the Hurwitz–Lerch zeta function, is a special function that generalizes the Hurwitz zeta function and the polylogarithm. It is named after Czech mathematician Mathias Lerch, who published a paper about the function in 1887.
