Fenton type minimax problems for sum of translates functions
Bálint Farkas, Béla NAgy, Szilárd Gy. Révész
Following P. Fenton, we investigate sum of translates functions , where $J:[0,1]\to {\underline{\mathbb{R}}}:=\mathbb{R}\cup\{-\inf…
A homeomorphism theorem for sums of translates
Bálint Farkas, Béla Nagy, Szilárd Gy. Révész
For a fixed positive integer consider continuous functions , that are concave and real valued on and on ,…
On the weighted Bojanov-Chebyshev Problem and the sum of translates method of Fenton
Bálint Farkas, Béla Nagy, Szilárd Gy. Révész
Minimax and maximin problems are investigated for a special class of functions on the interval . These functions are sums of translates of positive multiples of one kernel f…
Bernstein- and Markov-type inequalities
Sergei Kalmykov, Béla Nagy, Vilmos Totik
This survey discusses the classical Bernstein and Markov inequalities for the derivatives of polynomials, as well as some of their extensions to general sets.
Minimal energy point systems on the unit circle and the real line
Marcell Gaál, Béla Nagy, Zsuzsanna Nagy-Csiha +1
In this paper, we investigate discrete logarithmic energy problems in the unit circle. We study the equilibrium configuration of electrons and pairs of external protons o…
Minimal degree rational open up mappings and related questions
Sergei Kalmykov, Béla Nagy, Olivier Sète
We establish the existence and uniqueness of rational conformal maps of minimal degree for opening up arcs. In earlier results, the degree was exponential in . We also…
