Teaching period is over. During this period I was invited to give two talks but I didn´t have until now the opportunity to write about these here. In both occasions I talked about my favorite subject at the moment: integrable Hamiltonian systems with codimension-1 singularities.
Firstly, I was invited to give a talk at the second meeting of the GDR Quantum Dynamics that took place 24-26 March 2010 in Dijon. Besides my presentation, I had the opportunity to discuss with my colleagues in Dijon (Dominique Sugny, Pavao Mardešić, Michèle Pelletier, and Hans Jauslin) and with Dmitrií Sadovskií.
Secondly, I was invited to give a talk at the GSDE10 meeting that took place 17-22 May 2010 in Santa Marinella, a small seatown close to Rome. Giuseppe Gaeta is one of the organizers of the GSDE meetings and also of the more well known SPT conferences, the next one taking place 5-12 June 2011 in Polignano near Bari. In the meeting I had discussions with Ferdinand Verhulst and Giuseppe Pucacco, and I learned about the work by several Italian groups on symmetries of ordinary and partial differential equations.
