An extension of the Artin Braid Group is considered, with the introduc
tion of new operatores that generate double and triple intersections.
The extended Alexander theorem, relating intersecting closed braids an
d intersecting knots is proved for double and triple intersections, an
d a counter example is given for the case of quadruple intersections.
Intersecting knot invariants are also constructed via Markov traces de
fined on the intersecting braid algebra representations, and the exten
ded Turaev representation is discussed as an example.
