BEGIN:VCALENDAR VERSION:2.0 PRODID:-//hacksw/handcal//NONSGML v1.0//EN CALSCALE:GREGORIAN BEGIN:VEVENT LOCATION:Moscow\, Ordzhonikidze St.\, 3\, aud.470 DESCRIPTION:Using the Peakons (the exponential function) we will construct a family of  the Degasperis-Procesi type's equations for which the Peakons is a solitary wave traveling with the velocity c^(a-1). In the case a=2 we recover the quadratic Degasperis-Procesi equation and recall that Lin-Liu-K prove the orbital stability of the Peakons. In the case a=3 we will construct a fourth order stable evolution system (definition during the talk) with the cubic Degasperis-Procesi equation. Next\, we will prove that the second order stable evolution system is equivalent to the Isaac Newton Force. Finally\, we will make a numerical application constructed around the egyptian cubit.
