Davison Székelyhidi, László In his paper the author shows that Chebyshev polynomials of the first kind show up in relation with d’Alembert’s functional equation. Here we point out a similar property of Chebyshev polynomials concerning the square norm equation and we exhibit that the reason is due to close relations with hypergroups. 2002-01-01T00:00:00Z http://hdl.handle.net/11716/5705 Some consequences of a theorem of Liouville Schleiermacher, Adolf Let $E_n$ denote the $n$-dimensional Euclidean space and $S$ the group of Euclidean similarities. It is shown that the group $ (g, S)$ generated by $S$ and a single diffeomorphism $g$ outside $S$ has an orbit which is dense in $(E_n)^{n+1}$. 2002-01-01T00:00:00Z http://hdl.handle.net/11716/5704 La fonction d'indice et la fonction exponentielle Moszner, Zenon 2002-01-01T00:00:00Z
