Rate My Professor Florian Beyer

Florian Beyer is an Associate Professor in the Department of Mathematics and Statistics at the University of Otago, where he has served as Senior Lecturer since February 2015 and as Lecturer from November 2009 to 2015. Since November 2022, he has held the position of Associate Dean International for the Sciences Division. He earned his PhD from the University of Potsdam in September 2007 and his Diploma from the University of Münster in February 2004. Prior to his appointment at Otago, Beyer was a postdoctoral researcher at the Department of Mathematics, Université Pierre et Marie Curie in Paris from January to October 2009, and at Kungliga Tekniska Högskolan in Stockholm in 2008. His research centers on asymptotics and singular limits of solutions to partial differential equations, particularly Fuchsian partial differential equations that arise in mathematics and mathematical physics. Specific interests include global existence, stability, and asymptotics of Cauchy problems evolving towards singular times t=0, as well as singular initial value problems launched from t=0. In mathematical general relativity and cosmology, he studies nonlinear stability of cosmological models, Roger Penrose's cosmic censorship conjecture, asymptotic simplicity, Mixmaster dynamics, and computational aspects as a member of the University of Otago Gravity group.

Beyer has received the 2020 Division of Science Award for Outstanding Research Group and the 2013 Early Career Award from the New Zealand Mathematical Society. He served as a Research Member at the Mathematical Sciences Research Institute in Berkeley during the Fall 2013 program on Mathematical General Relativity and was invited to programs at the Erwin Schrödinger International Institute for Mathematics and Physics in Vienna (2022), the Institute Henri Poincaré in Paris (2015), and multiple workshops at Mathematisches Forschungsinstitut Oberwolfach (2012, 2015, 2018, 2021). His key publications include 'Relativistic perfect fluids near Kasner singularities' with T. A. Oliynyk (2024, Communications in Analysis & Geometry), 'Past instability of FLRW solutions of the Einstein-Euler-scalar field equations for linear equations of state p=Kρ with 0≤K<1/3' with E. Marshall and T. A. Oliynyk (2024, Physical Review D), 'Localized big bang stability for the Einstein-scalar field equations' with T. Oliynyk (2024, Archive for Rational Mechanics & Analysis), 'Future instability of FLRW fluid solutions for linear equations of state p=Kρ with 1/3 < K < 1' with E. Marshall and T. A. Oliynyk (2023, Physical Review D), and 'Asymptotically hyperboloidal initial data sets from a parabolic-hyperbolic formulation of the Einstein vacuum constraints' with J. Ritchie (2022, Classical & Quantum Gravity). Beyer has secured funding through University of Otago Research Grants, including 'Taming the beast of the cosmological big bang singularity: Dynamics and degrees of freedom' (2020), and as an Associated Investigator on Marsden and European Commission grants such as IPaDEGAN (2017).
