A Riemann-Hilbert problem for uncoupled BPS structures

Abstract

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