        "description":"Abstract:  In this talk, I will illustrate how classes of Fredholm Pfaffians, which can describe the eigenvalue distributions for orthogonal and symplectic matrix ensembles, can be computed in terms of canonical, auxiliary Riemann-Hilbert problems.\nThis is done by first algebraically manipulating the kernel of the Fredholm Pfaffian and then relating the resulting Pfaffian to a Riemann-Hilbert problem, assuming its main kernel is either of additive Hankel composition or truncated Wiener-Hopf type. One can then find asymptotic results for the Fredholm Pfaffian as a natural consequence of the Rieman-Hilbert problem characterisation.\nThis talk is based on my paper with Thomas Bothner, currently available in preprint on the arXiv: https:\/\/arxiv.org\/abs\/2511.23362. \n\n*To request access to the Zoom room, please contact Nathan Hayford at nhayford [ at ] umich.edu.*",
