91Essential spectrum — In mathematics, the essential spectrum of a bounded operator is a certain subset of its spectrum, defined by a condition of the type that says, roughly speaking, fails badly to be invertible .The essential spectrum of self adjoint operatorsIn… …
92Discrete Laplace operator — For the discrete equivalent of the Laplace transform, see Z transform. In mathematics, the discrete Laplace operator is an analog of the continuous Laplace operator, defined so that it has meaning on a graph or a discrete grid. For the case of a… …
93Fredholm determinant — In mathematics, the Fredholm determinant is a complex valued function which generalizes the determinant of a matrix. It is defined for bounded operators on a Hilbert space which differ from the identity operator by a trace class operator. The… …
94Davis–Putnam algorithm — The Davis–Putnam algorithm was developed by Martin Davis and Hilary Putnam for checking the validity of a first order logic formula using a resolution based decision procedure for propositional logic. Since the set of valid first order formulas… …
95Fredholm alternative — In mathematics, the Fredholm alternative, name after Ivar Fredholm, is one of Fredholm s theorems and is a result in Fredholm theory. It may be expressed in several ways, as a theorem of linear algebra, a theorem of integral equations, or as a… …
96Bring radical — In algebra, a Bring radical or ultraradical is a root of the polynomial :x^5+x+a, ,where a is a complex number. (The root is chosen so the radical of a real is real, and the radical is a differentiable function of a in the complex plane, with a… …
97Jordan matrix — In the mathematical discipline of matrix theory, a Jordan block over a ring R (whose identities are the zero 0 and one 1) is a matrix which is composed of 0 elements everywhere except for the diagonal, which is filled with a fixed element… …
98Elkies trinomial curves — In number theory, the Elkies trinomial curves are certain hyperelliptic curves constructed by Noam Elkies which have the property that rational points on them correspond to trinomial polynomials giving an extension of Q with particular Galois… …
99Gelfand-Mazur theorem — In operator theory, the Gelfand Mazur theorem is a theorem named after Israel Gelfand and Stanisław Mazur which states::A complex Banach algebra, with unit 1, in which every nonzero element is invertible is isomorphic to the complex numbers.In… …
100Cuticura soap — 1894 Advertisement for Cuticura Soap from Good Housekeeping Magazine Cuticura soap is an antibacterial medicated soap, in use since 1865 manufactured by Potter Drug and Chemical Company, George Robert White owner. It contains triclocarban instead …
