2-Local derivations and automorphisms on $B(H)$
Journal of Mathematical Analysis and Applications, 2011 The paper is devoted to 2-local derivations and 2-local automorphisms on the algebra $B(H)$ of all bounded linear operators on a Hilbert space $H.$ We prove that every 2-local derivation on $B(H)$ is a derivation. A similar result is obtained for automorphisms.

TWO METHODS OF DESCRIBING 2-LOCAL DERIVATIONS AND AUTOMORPHISMS [PDF]
Ural Mathematical JournalIn the present paper, we investigate 2-local linear operators on vector spaces. Sufficient conditions are obtained for the linearity of a 2-local linear operator on a finite-dimensional vector space. To do this, families of matrices of a certain type are

Weak 2-Local Inner Derivations of Semiprime ∗-Banach Algebras
MathematicsThis paper introduces and examines the concept of weak 2-local inner derivations and their relationship to P-2-local mappings. It is established that every such mapping on a semiprime ∗-Banach algebra with a faithful trace is a derivation, which also ...

2-local derivations on Virasoro algebras
Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences, 2019 The present paper is devoted to study 2-local derivations on infinite-dimensional Lie algebras over a field of characteristic zero. We show that every derivation on Virasoro algebra is inner and prove that all 2-local derivations on this algebra is a ...

2-Local derivations of infinite-dimensional Lie algebras [PDF]
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 Witt algebra are (global) derivations.

Density matrices in integrable face models
SciPost Physics, 2021 Using the properties of the local Boltzmann weights of integrable interaction-round-a-face (IRF or face) models we express local operators in terms of generalized transfer matrices.

$2$-local derivations on algebras of locally measurable operators [PDF]
Annals of Functional Analysis, 2013 The paper is devoted to 2-local derivations on the algebra $LS(M)$ of all locally measurable operators affiliated with a type I$_\infty$ von Neumann algebra $M.$ We prove that every 2-local derivation on $LS(M)$ is a derivation.
