I will stop having internet at home (I foresee in the next few days/weeks I am going to be disconnected of internet at home) thus my only chance/possibility to be connected to the site in next months/years (that is while I am user of this site MathOverflow) will be from a library with internet access or well from a call shop with internet access (I have no cell phone). I will always have attention, as soon as I can, to your answers, comments and bounties that I offer. Thank you very much for your attention and patience.
