However, rings of algebraic integers satisfy the weaker property... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Factorization Summary Factorization Factorization may also refer to more general decompositions of a mathematical object into the product of smaller or simpler objects. For example, every function may be factored into the composition of a surjective function with an injective function. Matrices possess many kinds of ma... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Field Arithmetic Summary Field_Arithmetic In mathematics, field arithmetic is a subject that studies the interrelations between arithmetic properties of a field and its absolute Galois group. It is an interdisciplinary subject as it uses tools from algebraic number theory, arithmetic geometry, algebraic geometry, model... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Finite field arithmetic Summary Finite_field_arithmetic In mathematics, finite field arithmetic is arithmetic in a finite field (a field containing a finite number of elements) contrary to arithmetic in a field with an infinite number of elements, like the field of rational numbers. There are infinitely many different ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Finite-dimensional distribution Summary Finite-dimensional_distribution In mathematics, finite-dimensional distributions are a tool in the study of measures and stochastic processes. A lot of information can be gained by studying the "projection" of a measure (or process) onto a finite-dimensional vector space (or fini... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Finiteness properties of groups Summary Finiteness_properties_of_groups In mathematics, finiteness properties of a group are a collection of properties that allow the use of various algebraic and topological tools, for example group cohomology, to study the group. It is mostly of interest for the study of infinite grou... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Five-term exact sequence Summary Five-term_exact_sequence In mathematics, five-term exact sequence or exact sequence of low-degree terms is a sequence of terms related to the first step of a spectral sequence. More precisely, let E 2 p , q ⇒ H n ( A ) {\displaystyle E_{2}^{p,q}\Rightarrow H^{n}(A)} be a first quadrant ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Flat convergence Summary Flat_convergence In mathematics, flat convergence is a notion for convergence of submanifolds of Euclidean space. It was first introduced by Hassler Whitney in 1957, and then extended to integral currents by Federer and Fleming in 1960. It forms a fundamental part of the field of geometric meas... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Hermitian matrix Rayleigh quotient Hermitian_matrices > Rayleigh quotient In mathematics, for a given complex Hermitian matrix M and nonzero vector x, the Rayleigh quotient R ( M , x ) , {\displaystyle R(M,\mathbf {x} ),} is defined as:: p. 234 For real matrices and vectors, the condition of being Hermitian reduces to ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Hermitian matrix Rayleigh quotient Hermitian_matrices > Rayleigh quotient {\displaystyle c.} Also, recall that a Hermitian (or real symmetric) matrix has real eigenvalues.

Hermitian matrix Rayleigh quotient Hermitian_matrices > Rayleigh quotient It is also used in eigenvalue algorithms to obtain an eigenvalue approximation from an eigenvector approximation. Specifically, this is the basis for Rayleigh quotient iteration. The range of the Rayleigh quotient (for matrix that is not necessar... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Hermitian matrix Rayleigh quotient Hermitian_matrices > Rayleigh quotient When the matrix is Hermitian, the numerical range is equal to the spectral norm. Still in functional analysis, λ max {\displaystyle \lambda _{\max }} is known as the spectral radius.
