Wikipedia:Hartley kernel#0 | In mathematics, the Hartley transform (HT) is an integral transform closely related to the Fourier transform (FT), but which transforms real-valued functions to real-valued functions. It was proposed as an alternative to the Fourier transform by Ralph V. L. Hartley in 1942, and is one of many known Fourier-related tran... |
Wikipedia:Hartman–Grobman theorem#0 | In mathematics, in the study of dynamical systems, the Hartman–Grobman theorem or linearisation theorem is a theorem about the local behaviour of dynamical systems in the neighbourhood of a hyperbolic equilibrium point. It asserts that linearisation—a natural simplification of the system—is effective in predicting qual... |

Wikipedia:Hasse derivative#0 | In mathematics, the Hasse derivative is a generalisation of the derivative which allows the formulation of Taylor's theorem in coordinate rings of algebraic varieties. == Definition == Let k[X] be a polynomial ring over a field k. The r-th Hasse derivative of Xn is D ( r ) X n = ( n r ) X n − r , {\displaystyle D^{(r)}... |
Wikipedia:Hasse–Schmidt derivation#0 | In mathematics, a Hasse–Schmidt derivation is an extension of the notion of a derivation. The concept was introduced by Schmidt & Hasse (1937). == Definition == For a (not necessarily commutative nor associative) ring B and a B-algebra A, a Hasse–Schmidt derivation is a map of B-algebras D : A → A [ [ t ] ] {\displayst... |
Wikipedia:Hat notation#0 | A "hat" (circumflex (ˆ)), placed over a symbol is a mathematical notation with various uses. == Estimated value == In statistics, a circumflex (ˆ), called a "hat", is used to denote an estimator or an estimated value. For example, in the context of errors and residuals, the "hat" over the letter ε ^ {\displaystyle {\ha... |
