Explosion of differentiability for equivalencies between Anosov flows on 3-manifolds
Mario Bessa, Sergio Dias, Alberto A. Pinto
For Anosov flows obtained by suspensions of Anosov diffeomorphisms on surfaces, we show the following type of rigidity result: if a topological conjugacy between them is differenti…
Explosion of smoothness for conjugacies between multimodal maps
Jose F. Alves, Vilton Pinheiro, Alberto A. Pinto
Let and be smooth multimodal maps with no periodic attractors and no neutral points. If a topological conjugacy between and is at a point in the nearby…
Universal Fluctuations of AEX index
Rui Gonçalves, Helena Ferreira, Alberto Pinto
We compute the analytic expression of the probability distributions F{AEX,+} and F{AEX,-} of the normalized positive and negative AEX (Netherlands) index daily returns r(t). Furthe…
Universal Fluctuations of the FTSE100
Rui Gonçalves, Helena Ferreira, Alberto Pinto
We compute the analytic expression of the probability distributions F{FTSE100,+} and F{FTSE100,-} of the normalized positive and negative FTSE100 (UK) index daily returns r(t). Fur…
Universality in DAX index returns fluctuations
Rui Gonçalves, Helena Ferreira, Alberto Pinto
In terms of the stock exchange returns, we compute the analytic expression of the probability distributions F{DAX,+} and F{DAX,-} of the normalized positive and negative DAX (Germa…
Universality in the stock exchange
Rui Gonçalves, Alberto Pinto
We analyze the constituents stocks of the Dow Jones Industrial Average (DJIA30) and the Standard & Poor's 100 index (S&P100) of the NYSE stock exchange market. Surprisingly, we dis…
