Quadratic Programming as an Extension of Classical Quadratic Maximization

Management Science, 1960
The article describes a procedure to maximize a strictly concave quadratic function subject to linear constraints in the form of inequalities. First the unconstrained maximum is considered; when certain constraints are violated, maximization takes place subject to each of these in equational (rather than inequality) form.

Constrained 0–1 quadratic programming: Basic approaches and extensions

open access: yesEuropean Journal of Operational Research, 2008
We describe the simplest technique to tackle 0-1 Quadratic Programs with linear constraints among those that turn out to be successful in practice. This method is due to and familiar to the Quadratic Assignment experts, even if it took some time to ...

Embeddability of quadratic extensions in cyclic extensions

Forum Mathematicum, 2007
Summary: For an algebraic number field \(K\) we study the quadratic extensions of \(K\) which can be embedded in a cyclic extension of \(K\) of degree \(2^n\) for all natural numbers \(n\), as well as the quadratic extensions which can be embedded in an infinite normal extension with the additive group \(\mathbb Z_2=\lim_{\leftarrow}\mathbb Z/2^n ...

An Extension Theorem for Quadratic forms

Results in Mathematics, 1987
Mit Hilfe eines Fortsetzungssatzes, der sich auf quadratische Formen auf Unterräumen eines n-Vektorraumes mit \(4\leq n\leq \infty\) über kommutativem Körper bezieht, werden Aussagen über quadratische Mengen mindestens dreidimensionaler projektiver Räume bewiesen.

A recurring theorem about pairs of quadratic forms and extensions: a survey

open access: yesLinear Algebra and Its Applications, 1979
This is a historical and mathematical survey of work on necessary and sufficient conditions for a pair of quadratic forms to admit a positive definite linear combination and various extensions ...

Extension of a quadratic transformation due to Exton

Applied Mathematics and Computation, 2009
By applying various known summation theorems to a general formula based upon Bailey's transform theorem due to Slater, Exton has obtained numerous new quadratic transformations involving hypergeometric functions of two and of higher order. Some of the results have typographical errors and have been corrected recently by Choi and Rathie.

The Groups LS and Morphisms of Quadratic Extensions

Mathematical Notes, 2001
Let \(U\) be a tubular neighborhood of a submanifold \(X\) of codimension \(q\) in the manifold \(Y\). There is a push-out square \(F\) defined by the diagram of fundamental groups of \(\partial U\), \(X\), \((Y \setminus X)\), and \(Y\). For this geometric situation one has associated Wall surgery obstruction groups \(LS_{n-q}(F)\).

Quadratic Field Extensions

1999
To complete this lab, you should be familiar with the construction of quotient rings of the ring of polynomials over a field F. You should also be familiar with irreducible polynomials over a field. This lab does not presume any other prior knowledge of field extensions. Doing Ring Lab 10 first would be helpful, but it is not necessary.
