SUMMARY:Vortrag von Prof. Serkan Gugercin
DESCRIPTION:Prof. Serkan Gugercin\nDepartment of Mathematics\nVirginia Polytechnic Institute and State University\nBlacksburg, VA, USA\n \nMonday 2022-12-12 1 p.m.\nIST Seminar Room 2.255 - Pfaffenwaldring 9 - Campus Stuttgart-Vaihingen \nAbstract\nWe start by studying the model reduction problem from a rational interpolation perspective\nand revisit some key findings such as the optimal rational interpolation in the H2-norm and\nrational-interpolants from data using the Loewner framework. We then study the concept of the\nBarycentric form of rational interpolants and show extensions to parametric dynamical\nsystems. If time allows, we will also visit nonlinear eigenvalue problems\n(NLEVPs), more specifically the contour-based techniques for NLEVPs and show that these\ntechniques for NLEVPs have strong connections to the classical realization theory such as the\nHo-Kalman algorithm. Once this connection is established, we then develop, using the Loewner-based\nrational interpolation theory, a systems-theory inspired framework for solving\nNLEVPs. \nBiographical Information\nSerkan Gugercin is a professor of Mathematics at Virginia Tech. He holds the Class of 1950\nProfessorship. He is also a core faculty member and a Deputy Director in the Division of\nComputational Modeling and Data Analytics. In 1992, he received his B.S. degree in Electrical and\nElectronics Engineering from Middle East Technical University, Ankara, Turkey; and his M.S. and\nPh.D. degrees in Electrical Engineering from Rice University, in 1999 and 2003, respectively. His\nprimary research interests are model reduction, data-driven modeling, numerical linear algebra,\napproximation theory, and systems and control theory.\n\nDr. Gugercin received the Ralph Budd Award for Research in Engineering from Rice University\nin 2003 for the best doctoral thesis in the School of Engineering; Teaching Award from Jacobs\nUniversity Bremen, in 2003; the National Science Foundation Early CAREER Award in Computational and\nApplied Mathematics in 2007; and the Alexander von Humboldt Research Fellowship in 2016.\n
