K\"ahler geometry and SUSY mechanics

We present two examples of SUSY mechanics related with K"ahler geometry. The first system is the N=4 supersymmetric one-dimensional sigma-model proposed in hep-th/0101065. Another system is the N=2 SUSY mechanics whose phase space is the external algebra of an arbitrary K"ahler manifold. The relation of these models with antisymplectic geometry is discussed.
