Formalized Mathematics, 2021 Summary In this article we further develop field theory [6], [7], [12] in Mizar [1], [2], [3]: we deal with quadratic polynomials and quadratic extensions [5], [4]. First we introduce quadratic polynomials, their discriminants and prove the midnight formula. Then we show that - in case the discriminant of

Convex hull of two quadratic or a conic quadratic and a quadratic inequality [PDF]
Mathematical Programming, 2016 This paper contributes to extending the development of strong valid inequalities to mixed integer conic quadratic programming. The analyis is based on results on the convex hull of open sets defined by two strict non-homogenuous quadratic inequalities in the reference [\textit{U. Yildiran}, IMA J. Math. Control Inf. 26, No.

Nonlinear Analysis, 2021 In this paper, we investigate a class of fractional hybrid differential equations with impulses, which can be seen as nonlinear differential equations with a quadratic perturbation of second type and a linear perturbation in partially ordered Banach ...

Note on the quadratic character of a quadratic unit [PDF]
Pacific Journal of Mathematics, 1981 1Φ Introduction* Let m be a positive squarefree integer, and let em denote the fundamental integral unit of the real quadratic field Q(λ/m), so that em = T + £Λ/m with positive integers T and U. Throughout, it is assumed that em has norm — 1, so that m = 1, 5 or 2(mod8), and all odd primes q dividing m satisfy q == I(mod4).

When Flexible Forms Are Asked to Flex Too Much
Journal of Agricultural and Resource Economics, 1994 Taylor series-based flexible forms cannot be interpreted as Taylor series approximations unless all data used in estimation lie in a region of convergence.

A New Non Quadratic Algorithm for Solving Non-Linear Optimization Problems [PDF]
Kirkuk Journal of Science, 2011 This paper proposes a new algorithm for non-linear optimization to modify and develop the conjugate gradient (CG) methods and to obtain a strong global convergence. This algorithm is derived and evaluated numerically against the standard (P/R and H/S)-CG

Identical equations for multiplicative functions [PDF]
Notes on Number Theory and Discrete MathematicsWe examine identical equations for multiplicative functions and certain special cases, such as totients and quadratics. We confine ourselves to identical equations expressing the value f(mn) (or the value f(m)f(n)) nontrivially in terms of the values f(m/
