Long finite time bubble trees for two co-rotational wave maps

Joachim Krieger, JosÃ© M. Palacios

We show that the energy critical Wave Maps equation from $R^{2 + 1}$ into $S^{2}$ , restricted to the $k = 2$ co-rotational setting, admits arbitrarily large numbers of…

Concentric bubbles concentrating in finite time for the energy critical wave maps equation

Jacek Jendrej, Joachim Krieger

We show that the energy critical Wave Maps equation from $R^{2 + 1}$ to $S^{2}$ and restricted to the co-rotational setting with co-rotation index $k = 2$ admits fini…
