Abstract

(Super)conformal mechanics in one dimension is induced by parabolic or hyperbolic/trigonometric transformations, either homogeneous (for a scaling dimension λ\lambda) or inhomogeneous (at λ=0\lambda=0, with ρ\rho an inhomogeneity parameter). Four types of (super)conformal actions are thus obtained. With the exclusion of the homogeneous parabolic case, dimensional constants are present. Both the inhomogeneity and the insertion of λ\lambda generalize the construction of Papadopoulos [CQG 30 (2013) 075018; arXiv:1210.1719]. Inhomogeneous DD-module reps are presented for the d=1d=1 superconformal algebras osp(12)osp(1|2), sl(21)sl(2|1), B(1,1)B(1,1) and A(1,1)A(1,1). For centerless superVirasoro algebras DD-module reps are presented (in the homogeneous case for N=1,2,3,4{\cal N}=1,2,3,4; in the inhomogeneous case for N=1,2,3{\cal N}=1,2,3). The four types of d=1d=1 superconformal actions are derived for N=1,2,4{\cal N}=1,2,4 systems. When N=4{\cal N}=4, the homogeneously-induced actions are D(2,1;α)D(2,1;\alpha)-invariant (α\alpha is critically linked to λ\lambda); the inhomogeneously-induced actions are A(1,1)A(1,1)-invariant.

29 pages. Final version to appear in J. Math. Phys. Two appendices and references added. It is pointed out that hyperbolic/trigonometric superconformal models are not ordinary supersymmetric theories
