摘要
We present a uniform construction of level 1 perfect crystals for all affine Lie algebras. We also introduce the notion of a crystal algebra and give an explicit description of its multiplication. This allows us to determine the energy function on completely and thereby give a path realization of the basic representations at in the homogeneous picture.
