This quantity introduces a wholly new pseudodifferential research at the line, the competition of which to the standard (Weyl-type) research may be stated to mirror that, in illustration idea, among the representations from the discrete and from the (full, non-unitary) sequence, or that among modular types of the holomorphic and alternative for the standard Moyal-type brackets. This pseudodifferential research is determined by the one-dimensional case of the lately brought anaplectic illustration and research, a competitor of the metaplectic illustration and ordinary analysis.

Besides researchers and graduate scholars drawn to pseudodifferential research and in modular kinds, the booklet can also attract analysts and physicists, for its techniques making attainable the transformation of creation-annihilation operators into automorphisms, at the same time altering the standard scalar product into an indefinite yet nonetheless non-degenerate one.
