Approximation of derivations and the superstability in random Banach ∗-algebras

Advances in Difference Equations, 2018
We prove that approximations of derivations on random Banach ∗-algebras are exactly derivations by using a fixed point method. Furthermore, we show that approximations of quadratic ∗-derivations on random Banach ∗-algebras are exactly quadratic ...

Deriving the Derivative

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.

Weak-local derivations and homomorphisms on C*-algebras [PDF]

, 2014
We prove that every weak-local derivation on a C*-algebra is continuous, and the same conclusion remains valid for weak*-local derivations on von Neumann algebras.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Homotopy derivations [PDF]

, 2014
We define a strong homotopy derivation of (cohomological) degree k of a strong homotopy algebra over an operad $$\mathcal {P}$$P. This involves resolving the operad obtained from $$\mathcal {P}$$P by adding a generator with “derivation relations”.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The Structure of D-Derivations and Their Decomposition in Lie Algebras

Mathematics
A D-derivation of a Lie algebra L is a linear map φ for which there exists a derivation D such that φ([x,y])=[φ(x),y]+[x,D(y)] for all x,y∈L. This paper presents explicit structural results concerning D-derivations in Lie algebras over arbitrary fields ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Characterization of derivations on strongly double triangle subspace lattice algebras by local actions

Open Mathematics
Let D $\mathcal{D}$ be a strongly double triangle subspace lattice on a nonzero complex reflexive Banach space and AlgD $\text{Alg}\mathcal{D}$ the associated subspace lattice algebra. Assume that F,G∈AlgD $F,G\in \text{Alg}\mathcal{D}$ and set R(F,G)=

Superstability of derivations on Banach ∗-algebras

Advances in Difference Equations, 2017
In this paper, we show that approximate derivations on Banach ∗-algebras are exactly derivations and also show that approximate quadratic ∗-derivations on Banach ∗-algebras are exactly quadratic ∗-derivations by the fixed point theorem.
