SUMMARY:Sangbum Yoo\, Spectral Data for Principal Higgs Bundles over a Singular Curve
DESCRIPTION:     Speaker\n\n\nSangbum Yoo\nGongju National University of Education\n\n\n\n\n\n\nSpectral data for Higgs bundles over a smooth curve has been studied by several mathematicians. The studies in this direction are originated by N.J.Hitchin. Specially\, it has contributed to the studies on the fibers of the Hitchin map. In this talk\, I will introduce spectral data for Higgs bundles over a smooth curve and over a singular curve\, and then present my ongoing project about spectral data for principal Higgs bundles over a singular curve.

SUMMARY:Seung-Jo Jung\, Hodge Ideals and Spectra of Hypersurface Singularities
DESCRIPTION:     Speaker\n\n\nSeung-Jo Jung\nJeonbuk National University\n\n\n\n\n\nRecently Mustata-Popa introduced a generalisation of multiplier ideals\, which is called Hodge ideals. This talk introduces the Hodge ideals and explains the relations with other invariants\, e.g. Bernstein-Sato polynomials\, Hodge spectra\, log canonical thresholds\, minimal exponents etc. Mainly this talk concerns the relation between Hodge ideals and Hodge spectra. This talk is based on the joint paper with I-K. Kim\, M. Saito\, and Y. Yoon.

SUMMARY:Hyungryul Baik\, Limits of Canonical Metrics in Low-dimensions
DESCRIPTION:     Speaker\n\n\nHyungryul Baik\nKAIST\n\n\n\n\n\nFor a tower of finite normal covers of graphs or surfaces\, one can consider a sequence of metrics on the base given by pull-back of canonical metric of the covers. We show that such a sequence has a limit and it depends only on the cover approximated by the tower up to scaling. The case of compact Riemann surface where the tower approximates the universal cover is due to Kazhdan. In this talk\, I will explain why one might be interested in such a problem\, give a brief introduction to the main tool – L2-theory\, and discuss some future directions. This talk is based on a joint work with Farbod Shokrieh and Chenxi Wu.
