A Riemann-Hilbert problem for uncoupled BPS structures
arXiv:1802.07655 · doi:10.1007/s00229-019-01115-y
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.
