It is used to define the theory of flat cohomology; it also plays a fundamental role in the theory of descent (faithfully flat descent). The term flat here comes from flat modules. There are se... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Flat cohomology Summary Fpqc_topology fppf stands for fidèlement plate de présentation finie, and in this topology, a morphism of affine schemes is a covering morphism if it is faithfully flat and of finite presentation. fpqc stands for fidèlement plate et quasi-compacte, and in this topology, a morphism of affine sche... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Flat cohomology Summary Fpqc_topology In the fpqc topology, any faithfully flat and quasi-compact morphism is a cover. These topologies are closely related to descent. The "pure" faithfully flat topology without any further finiteness conditions such as quasi compactness or finite presentation is not used much as is no... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Flat cohomology Summary Fpqc_topology Unfortunately the terminology for flat topologies is not standardized. Some authors use the term "topology" for a pretopology, and there are several slightly different pretopologies sometimes called the fppf or fpqc (pre)topology, which sometimes give the same topology. Flat cohomo... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Flatness (mathematics) Summary Flatness_(mathematics) In mathematics, the flatness (symbol: ⏥) of a surface is the degree to which it approximates a mathematical plane. The term is often generalized for higher-dimensional manifolds to describe the degree to which they approximate the Euclidean space of the same dimensi... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Folded spectrum method Summary Folded_spectrum_method In mathematics, the folded spectrum method (FSM) is an iterative method for solving large eigenvalue problems. Here you always find a vector with an eigenvalue close to a search-value ε {\displaystyle \varepsilon } . This means you can get a vector Ψ {\displaystyle ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |

Formal derivative Summary Formal_derivative In mathematics, the formal derivative is an operation on elements of a polynomial ring or a ring of formal power series that mimics the form of the derivative from calculus. Though they appear similar, the algebraic advantage of a formal derivative is that it does not rely on... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Conjecture Four color theorem Conjecture > Important examples > Four color theorem In mathematics, the four color theorem, or the four color map theorem, states that given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of th... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Conjecture Four color theorem Conjecture > Important examples > Four color theorem Möbius mentioned the problem in his lectures as early as 1840. The conjecture was first proposed on October 23, 1852 when Francis Guthrie, while trying to color the map of counties of England, noticed that only four different colors were... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Conjecture Four color theorem Conjecture > Important examples > Four color theorem A number of false proofs and false counterexamples have appeared since the first statement of the four color theorem in 1852. The four color theorem was ultimately proven in 1976 by Kenneth Appel and Wolfgang Haken. It was the first majo... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
