## Abstract

*not*decaying towards infinity. This gives the following consequences:

- 1.
We prove that there exist forward-in-time global solutions with arbitrarily large (and in fact infinite) initial bounded variation (BV) norms and initial Bondi masses.

- 2.
While general solutions with non-decaying data do not approach Minkowski spacetime, we show using the results of Luk and Oh (Anal PDE 8(7):1603–1674, 2014. arXiv:1402.2984) that if a sufficiently strong asymptotic flatness condition is imposed on the initial data, then the solutions we construct (with large BV norms) approach Minkowski spacetime with a sharp inverse polynomial rate.

- 3.
Our construction can be easily extended so that data are posed at past null infinity and we obtain solutions with large BV norms which are causally geodesically complete both to the past and to the future.
