Abstract

We explicitly describe the moduli space M s ( X , 3 ) M^s(X,3) of stable rank 2 parabolic bundles over an elliptic curve X X with trivial determinant bundle and 3 marked points. Specifically, we exhibit M s ( X , 3 ) M^s(X,3) as a blow-up of an embedded elliptic curve in ( C P 1 ) 3 (\mathbb {CP}^1)^3 . The moduli space M s ( X , 3 ) M^s(X,3) can also be interpreted as the S U ( 2 ) SU(2) character variety of the 3-punctured torus. Our description of M s ( X , 3 ) M^s(X,3) reproduces the known Poincaré polynomial for this space.
