Idea

In type IIB string theory there are bound states of D5-branes with NS5-branes. The bound state of pp \in \mathbb{Z} D5-branes with qq \in\mathbb{Z} NS5-branes is then called a (p,q)(p,q)-fivebrane or similar.

As pp and qq varies the species of (p,q)(p,q)5-branes form the lattice 2\mathbb{Z}^2 and are naturally acted on by the S-duality group SL(2,Z).

Properties

Charge conservation implies that at the brane intersection of the two a (1,1)(1,1)5-brane emerges stretched diagonally along v 5+v gv_5 + v_{g'}, i.e. along the multivector field v 0v 1v 2v 3v 4(v 5+v 5)v_0 v_1 v_2 v_3 v_4 (v_5 + v_{5'})

Aharony-Hanany 97, Sec. 3

The worldvolume-quantum field theory at the brane intersection point is a geometric engineering of D=5 N=1 SYM .

The T-dual perspective are D4/NS5-brane webs (Witten 97).

The result of connecting several such brane intersections are called (p,q)(p,q)-5brane webs (Aharony-Hanany-Krol 97).
