Keynote Speaker: Wang Suijie

      Abstract:

In this talk, we will explore the derived matroids and derived sequences of represented matroids. Firstly, the derived sequences are classified into three types: finite, cyclic, and divergent, which are completely characterized. Secondly, we determine all representable matroids whose derived matroids and dual matroids are isomorphic. Finally, as applications, the flats of the derived matroid give a classification on the translation deformations of hyperplane arrangements.

Speaker Introduction:

Wang Suijie, associate professor of the School of Mathematics, Hunan University, and doctoral supervisor, obtained his Bachelor's Degree from the Wuhan University, Master's Degree from the Peking University, and Doctor's Degree from the Hong Kong University of Science and Technology in 2010. Later, he worked as a postdoctoral researcher at the Hong Kong University of Science and Technology and the Academia Sinica. In 2013, he worked at the Hunan University. He mainly studies in hyperplane configuration, Matroid theory, Yang table theory and its combinatorial enumeration, and has published relevant scientific achievements in J. Combin. Theory Ser. A, J.
