We show that deformed Heisenberg algebra with reflection emerging in parabosonic constructions is also related to parafermions. This universality is discussed in different algebraic aspects and is employed for the description of spin-j fields, anyons and supersymmetry in 2+1 dimensions.

A new way how to calculate the off-shell renormalization functions within the R 2-gravity has been proposed. The one-loop renormaliza-tion group equations in the approach suggested have been constructed. The behaviour of effective potential for an massless scalar field interacting with the quantum gravitational field has been analyzed in this approach.

Using the N = 4 topological reformulation of N = 2 strings, we compute all loop partition function for special compactifications of N = 2 strings as a function of target moduli. We also reinterpret N = 4 topological amplitudes in terms of slightly modified N = 2 topological amplitudes. We present some preliminary evidence for the conjecture that N = 2 strings is the large N limit of Holomorphic...
