The Homflypt skein module . Let be an oriented -manifold. The Homflypt skein module of , denoted by , is the -module freely generated by isotopy classes of framed oriented links in including the empty link, quotiented by the Homflypt skein relations given in the following figure.
A linear connection on a Lie algebroid , with associated -derivative , is said to be compatible with the Lie algebroid structure of if there exists an -connection in , with associated -derivative , such that
Let be a solvable, non nilpotent Lie algebra. Then is called decomposable if
where is the nilradical of and an exterior torus of derivations, i.e., an abelian subalgebra consisting of -semisimple endomorphisms.
An satisfying the strict positivity and -summability assumptions (2-3) is called admissible , as is its associated free Lagrangian. The canonical antilinear isomorphism is given by
for all . Given a linear or antilinear operator , the conjugate transformation is given by
