WG5 Research Seminar - Talk by Özgür Yildirim

On May 05, 2022, Özgür Yildirim (Yildiz Technical University) will give a talk at 12:00 pm CEST about

"On the existence and Uniqueness of Weak Solution of the Coupled Sine-Gordon Equations".

The talk will be held online in Zoom. The zoom URL will be sent to all members of the WG5 and to all further colleagues who send a mail to Jan Giesselmann.


In the present talk, the existence and uniqueness of weak solution for the system of finite difference schemes for coupled sine-Gordon equations will be presented. 

In this study a novel first order of accuracy unconditionally stable difference scheme is considered. The variational method also known as the
energy method is applied to prove unique weak solvability. The unified numerical method for the approximate solution of this problem by combining the difference scheme and
the fixed point iteration will be introduced. A test problem  and results of numerical experiments will be presented.
