Our main focus are mathematical and physical models of shape evolution with emphasis on geophysical and planetological applications, such as sand grains, pebbles, ventifacts, rock profiles, asteroids.
Our research group operates at the Budapest University of Technology and Economics and it is supported on a 5 year (2017-2022), renewable special grant from the Hungarian Academy of Sciences. Our goal is to collect, develop and apply existing mathematical models and test the models versus existing and self-produced experimental and field data. Ultimately we would like to gain insight on geophysical history based on current size and shape measurements.
At this year’s Student Research Conference 3 presentations were related to Morphodynamics: Krisztina Regős (1st Prize + Pro Progressio Special Prize), Dániel Csallóközi (2nd Prize + Csonka Pál Special Prize), Péter Tamás Varga (3rd Prize).
Sir Michael Berry is going to give a lecture on 12th December 2018., at BME room K134 with a title of ‘Nature’s optics and our understanding of light’.
Our guest lecturer Snorre H. Christiansen gave us his talk titled ‘Finite element complexes for the Stokes equation’.
Our guest lecturer Daniel Barreto from Edinburgh Napier University gave us his talk titled ‘Contact force entropy coordinates – Their relationship with critical states and shearing resistance’.
A recently published paper in Scientific Reports, András A. Sipos, Gábor Domokos, Douglas J. Jerolmack: Shape evolution of ooids: a geometric model, presents a simple geometric model that predicts equilibrium shapes for carbonate particles known as ooids.
The paper Explaining the Elongated Shape of ‘Oumuamua by the Eikonal Abrasion Model (Gábor Domokos, András Á. Sipos, Gyula M. Szabó, Péter L. Várkonyi) was followed by increased media attention.
It is now available online.
