    "abstract": "A study of secondary instabilities in ac-driven electroconvection of a\nplanarly aligned nematic liquid crystal is presented. At low frequencies one\nhas a transition from normal rolls to a zig-zag pattern and at high frequencies\na direct transition from normal to abnormal rolls. The crossover defines a\ncodimension-2 point. This point is also the origin of a line of homoclinic\nbifurcations, which enable the transition from zig-zags to abnormal rolls at\nlower frequencies.",
