Derivatives and Derivative Markets

2006
In this chapter we introduce readers to the nuts and bolts of derivatives. The objective is, however, different from that found in an introductory finance textbook. There are now many good texts on derivatives, explaining how they are priced and strategies for trading them. There is no point in repeating that content. Rather, this chapter seeks to show

Derived Equivalences As Derived Functors

Journal of the London Mathematical Society, 1991
In [J. Lond. Math. Soc., II. Ser. 39, No.3, 436-456 (1989; Zbl 0642.16034)], we proved that two algebras \(\Lambda\) and \(\Gamma\) are ``derived equivalent'', meaning that the derived category of modules for \(\Lambda\) is equivalent to that for \(\Gamma\), precisely when \(\Gamma\) is isomorphic to the endomorphism ring of what we called a ``tilting ...

The Derivative and Higher Derivatives

2007
The derivative of a function, even if it exist everywhere, can be discontinuous. For example, if \(f\left( x \right) = {x^2}\sin \frac{1}{x}\), for x ≠ 0, f(0) = 0, then for x ≠ 0, \(f'\left( x \right) = - \cos \frac{1}{x} + 2x\sin \frac{1}{x}\), which does not tend to any limit as x tends to 0, although f′(0) exists and equals 0, as may be easily ...

Derived Varieties and Derived Equational Theories

International Journal of Algebra and Computation, 1998
This paper describes a derivation process for varieties and equational theories using the theory of hypersubstitutions and M-hyperidentities. A hypersubstitution σ of type τ is a map which takes each n-ary operation symbol of the type to an n-ary term of this type.

On derivability

Journal of Symbolic Logic, 1937
1. The notion of derivability. Italic capitals, with or without subscripts, will be used as variables. They are to take as values some manner of elements which may for the present be left undetermined. Now let us consider abstractly the notion of the derivability of an element X from one or more specified elements by a series of steps of a specified ...

ON (σ, τ)-n-DERIVATIONS IN NEAR-RINGS

, 2013
In the present paper, we introduce the notion of (σ, τ)-n-derivation in near-ring N and investigate some properties involving (σ, τ)-n-derivations of a prime near-ring N which force N to be a commutative ring.

Dérivations bilio-digestives dans la chirurgie palliative du cancer de la tête du pancréas : à propos de 45 cas.

, 2012
Le but de ce travail etait d’evaluer l’importance de la derivation bilio-digestive dans le traitement palliatif des cancers de la tete du pancreas. Il s’agissait d’une etude retrospective sur une periode de 11 ans et 6 mois (janvier 1999 a juin 2010 ...

Cubic derivations on Banach algebras

Acta Mathematica Vietnamica, 2013
Let A be a Banach algebra and X be a Banach A-bimodule. A mapping D: A⟶X is a cubic derivation if D is a cubic homogeneous mapping, that is, D is cubic and D(λa)=λ3D(a) for any complex number λ and all a∈A, and D(ab)=D(a)⋅b3+a3⋅D(b) for all a,b∈A.

Derivations in Hyperrings and Prime Hyperrings

, 2013
In this paper we introduce derivations in Krasner hyperrings and derive some basic properties of derivations. We also prove that for a strongly dierential hyperring R and for any strongly dierential hyper- ideal I of R, the factor hyperring R/I is a ...
