摘要：
We study the splitting process of a multiply quantized vortex for a trapped highly oblate Bose-Einstein condensate in an optical lattice. Fourfold or sixfold splitting patterns are found in the dynamical evolution in square or triangular optical lattices, respectively. The relaxation time and angular momentum are also investigated to explore the properties of splitting. We find one singly quantized vortex or antivortex could be finally stabilized at the trap center.
