Signs and Society, 2018 AbstractThe anthropology of finance has been dominated by ethnographic field research and the performativity thesis advanced by Donald Mackenzie and Michel Callon. This essay takes a different tack and proposes a semiotic framework to look at the central concept in derivative finance, that of volatility.

2-Local derivations of infinite-dimensional Lie algebras
Journal of Algebra and its Applications, 2019 In the present paper, we study 2-local derivations of infinite-dimensional Lie algebras over a field of characteristic zero. We prove that all 2-local derivations of the Witt algebra as well as of the positive Witt algebra and the classical one-sided ...

On bilateral derivates and the derivative [PDF]
Transactions of the American Mathematical Society, 1975 In this paper we prove a new result on the monotonicity of a function in terms of its bilateral derivates, and obtain from it extensions of several existing results on such derivates and the derivative of a function. Let f : R → R f:R \to R , where R R denotes the set of real ...

Commutativity Results on Prime Rings With Generalized Derivations [PDF]
Engineering and Technology Journal, 2016 Let R be a prime ring. For nonzero generalized derivations F and G associated with the same derivation d, we prove that if d≠0, then R is commutative, if any one of the following conditions hold: (1) [F(x), G(y)] 0, (2) F(x)oG(y) 0, (3) F(x)oG(y ...

Hasse--Schmidt derivations versus classical derivations
, 2020 In this paper we survey the notion and basic results on multivariate Hasse--Schmidt derivations over arbitrary commutative algebras and we associate to such an object a family of classical derivations. We study the behavior of these derivations under the

The derivations of some evolution algebras [PDF]
, 2013 In this work we investigate the derivations of n−dimensional complex evolution algebras, depending on the rank of the appropriate matrices. For evolution algebra with non-singular matrices we prove that the space of derivations is zero.

A Formalization of Agree as a Derivational Operation
Biolinguistics, 2023 Using the framework based on set-theory, I develop a formal definition of Agree as a syntactic operation. I begin by constructing a formal definition of a version of long-distance Agree in which a structurally higher element values a feature on a ...

A Parallel Derivation Theory of Adjuncts
Biolinguistics, 2022 I present and argue for a theory of adjuncts according to which, adjuncts and their respective hosts are derived as separate, parallel objects that are not combined until forced to by the process of linearization. I formalize the notion of the workspace,

Generalized derivations of (color) n-ary algebras [PDF]
, 2015 We generalize the results of Leger and Luks about generalized derivations of Lie algebras to the case of color -ary -algebras. Particularly, we prove some properties of generalized derivations of color -ary algebras; prove that a quasi-derivation algebra

IO vs OI in Higher-Order Recursion Schemes [PDF]
, 2012 We propose a study of the modes of derivation of higher-order recursion schemes, proving that value trees obtained from schemes using innermost-outermost derivations (IO) are the same as those obtained using unrestricted derivations.
