title: Front instabilities in a forced oscillatory medium with global coupling.
abstract: We study a two-dimensional, locally and globally coupled oscillatory system that is subjected to external forcing at a frequency equal to twice its natural frequency. It is shown that the onset of an Ising-Bloch transition is preceded by novel front instabilities: a pattern formation instability, wave trains along the front, and a weak turbulence in the frontal patterns.
