On the Invariant System of a Pair of Connexes

O. E. Glenn
1916 Transactions of the American Mathematical Society  
The theoretical part of this paper treats of a transvectant operation between two general connexes wherein the variables are ternary and ( u ) contragredient to ( x ). This operation, defined by polarization, gives all invariant formations of the simultaneous system of two connexes. Our transvectant, of four indices,
