Abstract
A finite ringed space is a ringed space whose underlying topological space is finite. The category of finite ringed spaces contains, fully faithfully, the category of finite topological spaces and the category of affine schemes. Any ringed space, endowed with a finite open covering, produces a finite ringed space. We study the homotopy of finite ringed spaces, extending Stong’s homotopy classification of finite topological spaces to finite ringed spaces. We also prove that the category of quasi-coherent modules on a finite ringed space is a homotopy invariant.
