[en] The aim of this paper is to study some brackets defined on (τ, σ )-derivations sat-
isfying quasi-Lie identities. Moreover, we provide examples of (p, q)-deformations
of Witt and Virasoro algebras as well as sl(2) algebra. These constructions gen-
eralize the results obtained by Hartwig, Larsson and Silvestrov on σ -derivations,
arising in connection with discretizations and deformations of algebras of vector
fields.
