Tags

A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

 Type to find tags:
 direct-sum× 42 automorphic-forms× 42 bifurcation× 42 hodge-theory× 42 The study of relations between, one the one hand, the topology of a smooth manifold as encoded in the cohomology groups, and on the other, the set of solutions to the Laplace operator on differential … mean-square-error× 42 magma-cas× 41 a computer algebra system distributed by the University of Sydney, and designed for solving problems in algebra, number theory, geometry and combinatorics. nets× 41 a generalization of a sequence where a directed set is used as the index set instead of positive integers. Convergence of nets can be defined in a similar way as convergence of sequences. … prime-twins× 41 For questions on prime twins. symmetric-functions× 41 grassmannian× 41 fuzzy-logic× 41 combinatorial-designs× 41 For questions about Combinatorial design theory, a part of combinatorial mathematics that deals with the existence, construction and properties of systems of finite sets whose arrangements satisfy gen… utility× 41 A tag for all questions involving a type of utility function. transformational-geometry× 40 theta-functions× 40 For questions about $\theta$ functions. deformation-theory× 40 The study of how mathematical objects (complex manifolds, associative algebras, Lie algebras) can be deformed into similar mathematical objects, at least infinitesimally. group-rings× 40 a ring constructed from a group $G$ and ring $R$. A special case of this construction is group algebra, which occurs naturally in representation theory. research× 40 matrix-rank× 40 For questions regarding the rank of matrices in linear algebra. levy-processes× 39 Question related to Lévy processes, i.e. stochastically continuous processes with independent, stationary increments. multiplicative-function× 39 In number theory, a multiplicative function is a function defined on positive integers such that f(ab)=f(a)f(b) for a,b coprime. E.g. Euler's totient function, sum of divisors and number of divisor… homogeneous-equation× 39 experimental-mathematics× 39 dedekind-domain× 39 algebras× 39 For questions about algebras, their properties, and their structures. abelian-varieties× 39 tessellations× 39 For question on Tessellations, the process of creating a two-dimensional plane using the repetition of a geometric shape with no overlaps and no gaps. mathematicians× 38 Questions about mathematicians and their lives. minimal-surfaces× 38 Question on minimal surfaces, or surfaces that have zero mean curvature. rngs× 38 an associative ring without necessarily having a multiplicative identity (rng = ring - $i$dentity). stationary-processes× 38 For questions about strictly stationary or stationary in the wide sense sequences or processes. Questions about deterministic stationary processes (in the case of discrete dynamical systems) are welco… statistical-mechanics× 37 splitting-field× 37 The splitting field of a polynomial with coefficients in a field, F, is the smallest field extension to F such that the polynomial decomposes into linear factors. Often used with Galois-theory tag. popular-math× 37 Question on bits and pieces of mathematics that show up in popular media (TV, movies, comics, etc.) absolute-convergence× 37 for questions related to absolute convergence a series. dimensional-analysis× 37
