Cubic primals in [4] with polar heptahedra*
Published online by Cambridge University Press: 14 February 2012
Synopsis
This note sets out from the observation that it is not, in general, possible to express a homogeneous cubic polynomial in five variables as a sum of cubes of seven linear forms. Some of the geometry, to which particular cubics which do happen to be so expressible give rise, is described. Further particularisations are mentioned, and one such cubic investigated in some detail.
