Denny Otten

Dr. Denny Otten is a Research Fellow at the Faculty of Mathematics, Bielefeld University since April 2014, affiliated with the Collaborative Research Center (SFB 701) under Prof. Dr. Wolf-Jürgen Beyn. His research focuses on computational and analytical studies of rotating waves in parabolic systems, numerical methods for equivariant evolution equations, and the freezing method for wave dynamics.

His work involves analyzing rotating waves in reaction-diffusion systems, nonlinear problems for complex-valued Ornstein-Uhlenbeck operators, and numerical approximation techniques using Comsol Multiphysics. Key areas include spectral analysis of localized waves, stability analysis, and the interplay between different wave phenomena such as traveling, oscillating, and rotating waves.

Otten has presented his research at conferences including the SIAM Conference on Nonlinear Waves and Coherent Structures (2016) and the Patterns of Dynamics conference (2016). His contributions span theoretical analysis and computational methods, with a focus on equivariant systems and their applications in mathematical physics.
