is Zelmanov's tensor constructed by him on the basis of the non-commutativity of the second chronometrically invariant derivatives of an arbitrary spatial vector taken in a given three-dimensional spatial section
Aimed at graduate students and researchers, topics include the construction of graded differential algebra with ternary differential, thoughts on non-commutativity in membranes and matrices, discretized Virasoro algebra, Picard groups in rational conformal field theory, Shapovalov forms for Poisson Lie superalgebras, time-space and space-times, the index problem on manifolds with edges, quantum groups and bounded symmetric domains, quantization in deformation and monoidal Morita equivalence.
Note that the non-commutativity is a quantization effect.
