Abstract
We study the Riemann-Hilbert problem attached to an uncoupled BPS structure proposed by Bridgeland in ("Riemann-Hilbert problems from Donaldson-Thomas theory I"). We show that it has "essentially" unique meromorphic solutions given by a product of Gamma functions. We reconstruct the corresponding connection.
