A note on the non-existence of $σ$ -model solitons in the 2+1 dimensional AdS gravity

Piotr Bizoń, Arthur Wasserman

We show that the gravitating static soliton in the 2+1 dimensional O(3) $σ$ model does not exist in the presence of a negative cosmological constant.

Periodic self-similar wave maps coupled to gravity

P. Bizoń, S. Szybka, A. Wassserman

We continue our studies of spherically symmetric self-similar solutions in the SU(2) sigma model coupled to gravity. Using mixed numerical and analytical methods we show existence…
