We study the role of boundary conditions on the one loop partition function the N=2 chiral multiplet of R-charge Δ on AdS2 ×S1. The chiral multiplet is coupled to a background vector multiplet which preserves supersymmetry. We implement normalizable boundary conditions in AdS2 and develop the Green’s function method to obtain the one loop determinant. We evaluate the one loop determinant for two different actions: the standard action and the Q-exact deformed positive definite action used for localization. We show that if there exists an integer n in the interval D: (Δ−12L,Δ2L), where L being the ratio of radius of AdS2 to that of S1, then the one loop determinants obtained for the two actions differ. It is in this situation that fields which obey normalizable boundary conditions do not obey supersymmetric boundary conditions. However if there are no integers in D, then fields which obey normalizable boundary conditions also obey supersymmetric boundary conditions and the one loop determinants of the two actions precisely agree. We also show that it is only in the latter situation that the one loop determinant obtained by evaluating the index of the D10 operator associated with the localizing action agrees with the one loop determinant obtained using Green’s function method.
