摘要

。对于具有Legendrean(或lagrange)接触结构E⊕F∧TM的流形M，我们给出了商束TM/F上不变部分连接的初等构造。这允许我们开发一个相对牵引器微积分的na¨ıve版本，并构造一个二阶不变微分算子，该算子是由部分连接导出的第一个相对BGG算子。

Elementary relative tractor calculus for Legendrean contact structures

. For a manifold M endowed with a Legendrean (or Lagrangean) contact structure E ⊕ F ⊂ TM , we give an elementary construction of an invariant partial connection on the quotient bundle TM/F . This permits us to develop a na¨ıve version of relative tractor calculus and to construct a second order invariant diﬀerential operator, which turns out to be the ﬁrst relative BGG operator induced by the partial connection.
