Ingram Lectureship

After he retired following the Fall 2002 semester, Professor W.T. Ingram, who was department chair from 1989-1998, generously set up an endowed fund to be used to bring well-known mathematical scientists to Rolla to give lectures on their work.  All Ingram Lectures are open to the entire S&T community, and are widely advertised on campus.  Visitors brought here under this program usually give two lectures, one of a general nature and accessible to students, and another more advanced aimed at faculty (though students are certainly welcome).

FALL 2018 Colloquia



Asymptotic behavior of quadratic Klein-Gordon equation in two dimensions

Satoshi Masaki
Associate Professor

Friday, September 21, 2018
4:00-5:15 PM
Rolla Bldg G-5

In this talk, we discuss asymptotic behavior of solutions to nonlinear Klein-Gordon equation with the gauge invariant power type nonlinearity of the critical order. By using the expansion of the nonlinearity, we see that there exist solutions which asymptotically behaves like a free solution with logarithmic phase correction. It will turn out that the behavior of a complex-valued solution is much complicated than that of a real-valued solution.

Dr. Masaki earned his PhD in Mathematics from Kyoto University in the Spring of 2009 under the supervision of Yoshio Tsutsumi. He began his career at Gakushuin University in Spring 2010 as an Assistant Professor. In Fall 2012, he moved to Hiroshima University as an Associate Professor. Since Spring 2016, he has been an Associate Professor at Osaka University. Dr. Masaki's main research interests lie in the areas of harmonic analysis and nonlinear dispersive equations, with a primary focus on the asymptotic behavior of solutions to nonlinear Schrödinger equations.
