TL;DRAbstract

For the Special Session of Aimeta : “The analytical approach to inviscid two dimensional vortex dynamics. Is it only an ancient issue?” SUMMARY How powerful modern-day computers could be, despite these times of CFD twilight, what the calculations of today are trying to solve are still the same equations which Euler put to paper more than two centuries ago. Now, a 260-somethings-years-old issue is undoubtedly old. Anyway, if he were to return for following a vortex on the plane, Euler also would maybe prefer ,to numerics and a lagrangian pursuit, a same attempt tried by analysis and eulerianly. This, in essence, is what essayed below.
