[phys4phys] Seminar Ivan Hristov, 11. Oct., 12:00

[Veljko Dmitrasinovic]

Dear colleagues,

You are cordially invited to the lecture by prof. dr. Ivan Hristov,
Faculty of Mathematics and Informatics, Sofia University, Sofia, 
Bulgaria,
organized by the COE for non-equilibrium processes, which will be held
on Wednesday, 11th October 2023, at 12:00 in the library room "Dragan 
Popović",
Institute of Physics.

The title of the talk is:
"Computing periodic orbits for the planar three-body problem with 
Newton's method"

Abstract of the talk:

In this seminar Newton's method for computing high-precision periodic 
orbits for the planar three-body problem will be discussed [1]. 
Symmetric initial configuration with parallel velocities [2] and the 
free-fall initial configuration [3,4] are considered. We solve the 
system of ODEs with the multiple precision high-order Taylor series 
method [5]. A modification of the method with better convergence 
properties is also introduced.
