The hardcore constraint permits no more than one fermion per lattice site. Such a system is, eventually, strongly interacting, and has no small parameter expansion. I will discuss how spin and charge dynamics factorize at the level of correlation functions. The problem has a long history, and I will show a trick, eventually reducing the complete solution to a few elementary algebraic manipulations.
