Abstract: 

BPS structures locally describe the space of Bridgelandstability conditions of a CY3 category together with a generalisedDonaldson-Thomas theory. On the other hand, Riemann-Hilbert problemsare inverse problems in the theory of differential equations. I willdiscuss a Riemann-Hilbert problem naturally attached to a BPSstructure, focusing in the uncoupled case.
