Bueker (1948), investigating the effects of implanted tumors on the development of the nervous system of the chick embryo, found that sarcoma 180 caused enlargement (hypertrophy and hyperplasia) of the spinal ganglia in the segments adjacent to it. The motor columns, however, were not enlarged. He suggested that the sarcoma provided a selective periphery with mechanical and histochemical proper...

Given any simple Lie superalgebra g, we investigate the structure of an arbitrary simple weight g-module. We introduce two invariants of simple weight modules: the shadow and the small Weyl group. Generalizing results of Fernando and Futorny we show that any simple module is obtained by parabolic induction from a cuspidal module of a Levi subsuper-algebra. Then we classify the cuspidal Levi sub...
