Peng Ren,Zhiyuan Tian,Zeyu Wang,Xin Li,Xia Wang,Tao Zhao,Ming ShengIn this Chapter we consider operators of the form A = F.Ф(ξ)F., where F is the Fourier transform on ., and Ф is a positively homogeneous function of complex degree ., i.e. Ф(.) = .Ф(. for . ∈., . > 0. We study the problem of continuity of the maps A:.(.) → . (.) and A:.. (.., ..) → .(., ..

For the structure of an algebra the existence of ., i.e. of elements e ≠ 0 with e. = e, is of particular interest. But also from the biological aspect the existence of such elements is of interest because the equilibria of a population which can be described by an algebra correspond to idempotents of this algebra.
