Abstract
In this paper, we present a straightforward pictorial representation
of the double affine Hecke algebra (DAHA) which enables us to
translate the abstract algebraic structure of a DAHA into an intuitive
graphical calculus suitable for a physics audience. Initially, we define the
larger double affine Q-dependent braid group. This group is constructed
by appending to the braid group a set of operators Qi, before extending
it to an affine Q-dependent braid group. We show specifically that the
elliptic braid group and the DAHA can be obtained as quotient groups.
Complementing this, we present a pictorial representation of the double
affine Q-dependent braid group based on ribbons living in a toroid.
We show that in this pictorial representation, we can fully describe any
DAHA. Specifically, we graphically describe the parameter q upon which
this algebra is dependent and show that in this particular representation
q corresponds to a twist in the ribbon.
