- Surprising results in the theory of inviscid flows
- Mgr. Ondřej Kreml, PhD
- MÚ AV ČR
- (seminář v angličtině)
The flow of inviscid incompressible fluid is described by the Euler equations derived over 250 years ago. Although these equations play a fundamental role in fluid mechanics for centuries, they are still a source of plenty of open problems. Little is known about classical solutions in 3D, on the other hand weak solutions behave badly. In 1993, Scheffer proved the existence of nontrivial weak solution to the Euler equations with compact support in time. In 2009, De Lellis and Székelyhidi derived a theory capable of proving not only the result of Scheffer in a much simpler way but also many other surprising results connected with nonuniqueness of weak solutions of incompressible and also compressible Euler equations.

- What has numerical relativity taught us?
- Dr. David Hilditch
- Theoretisch-Physikalisches Institut Friedrich-Schiller-Universität, Jena
- (seminář v angličtině)
I will give an introduction to numerical relativity. Focus will be on the principle considerations for doing numerics well, including PDEs analysis, building formulations and high performance computing. I will give an overview of the results obtained in the last decade in the evolution of compact binary spacetimes. Afterwards I will describe work done in the last few years in developing the Z4c formulation of numerical relativity as the successor to BSSNOK.
(The talk will be followed by two more technical lectures today and tomorrow at 13:10.)

- Astrophysical Levy Flights
- Prof. Re'em Sari
- Racah Institute of Physics, Hebrew University, Jerusalem
- (seminář v angličtině)
Levy flights are a form of random walk, where the step size is drawn from a distribution with
infinite second moment. They appear quite ubiquitously in nature,
like in the motion of Spider Monkeys or Albatrosses in their search for food, as well as in the stock market.
We discuss their implication to astrophysical situations including eccentricity of planetesimals,
eccentricities of binaries, formation of the Oort Cloud, collisional spins of asteroids, and
astrometry and photometry of IR sources in the galactic center.

- Vazeni a mili, v pondeli 18. kvetna probehlo Valne shromazdeni Ucene Spolecnosti v Aule Magne Karolina dopoledne a odpoledne v Modre poslucharne na rektorate. Docela rozumne tam mluvil vicepremier Belobradek a zajimave pak 3 eminentni brtisti vedci: Lord Rees (Astronomer Royal atd atd), Prof G. Boulton (expert na more a ledovce) a Prof Sir B. Heap (biolog). Dopoledne meli kratsi prednasky na obecnejsi temata, odpoledne specifictejsi prednasky. Hosi z rektoratu vyrobili docela kvaltini video zaznamy, ktere si dovoluji preposlat vasi pozornosti, resp. nepozornosti.
