R‐matrix approach to quantum superalgebras suq(m‖n)

Quantum superalgebras suq(m‖n) are studied in the framework of R‐matrix formalism. Explicit parametrization of L(+) and L(−) matrices in terms of suq(m‖n) generators are presented. We also show that quantum deformation of nonsimple superalgebra su(n‖n) requires its extension to u(n‖n).
