Deriving derivatives of derivative securities

The Journal of Computational Finance, 2000
We use various techniques to simplify the derivations of "greeks" of path-independent claims in the Black-Merton-Scholes model. We first interpret delta, gamma, speed, and other higher order spatial derivatives of these claims as the values of certain quantoed contingent claims.

Ellipticine derivatives

Journal of Medicinal Chemistry, 1975
Several acyloxy and alkyl derivatives of ellipticine have been prepared. In addition, a modified synthesis leading to the hitherto unobtainable 8,9-dimethoxy- and 8,9-methylenedioxyellipticines is described. Some of the derivatives described herein exhibit antitumor activity.

Towards a derivation of holographic entanglement entropy

, 2011
We provide a derivation of holographic entanglement entropy for spherical entangling surfaces. Our construction relies on conformally mapping the boundary CFT to a hyperbolic geometry and observing that the vacuum state is mapped to a thermal state in ...

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 ...

NORMAL DERIVATIONS AND SEQUENT DERIVATIONS

Journal of Philosophical Logic, 2008
Normal proofs in natural deduction systems for intuitionistic logic roughly correspond to cut-free sequent derivations. This article elaborates on this correspondence. First, a system \(\mathcal{N}\) for natural deductions and a system \(\mathcal{S}\) for sequent derivations are introduced.

Tetramethylcyclopentadienylselenium derivatives

Organic & Biomolecular Chemistry, 2005
Bis(1,2,3,4-tetramethylcyclopentadienyl)selane (1) has been prepared by the reaction of tetramethylcyclopentadienyllithium (Cp(t)Li) with selenium bis(diethyldithiocarbamate). Treatment of Cp(t)Li with elemental selenium, followed by air oxidation, led to loss of the allylic hydrogen atom, and formation of the novel tricyclic compound 1,4,5,6,7,10,11 ...

[Electrocardiograms: derived derivations!]

Revue de l'infirmiere, 2018
Simple and non-invasive, the electrocardiogram is a basic examination for studying how the cardiac muscle functions. Very commonly used, it nonetheless requires great rigour when applying the electrodes to avoid false results that can be harmful to appropriate care for the patient. A reminder of good practices.
