Kondratiev Y, Kuna T, Oliveira MJ. Extension of explicit formulas in Poissonian white noise analysis using harmonic analysis on configuration spaces. In: Condensed Matter Physics. CONDENSED MATTER PHYSICS. Vol 11. INST CONDENSED MATTER PHYSICS NATL ACAD SCIENCES UKRAINE; 2008: 237-246.Harmonic analysis on configuration spaces is used in order to extend explicit expressions for the images of creation, annihilation, and second quantization operators in L-2-spaces with respect to Poisson point processes to a set of functions larger than the space obtained by directly using chaos expansion. This permits, in particular, to derive an explicit expression for the generator of the second quantization of a sub-Markovian contraction semigroup on a set of functions which forms a core of the generator
