Center node: "bifinite chu spaces"
  Abstract: This paper studies colimits of sequences of finite Chu spaces and their#N#ramifications. Besides generic Chu spaces, we consider extensional and#N#biextensional variants. In the corresponding categories we first characterize#N#the monics and then the existence (or the lack thereof) of the desired#N#colimits. In each case, we provide a characterization of the finite objects in#N#terms of monomorphisms/injections. Bifinite Chu spaces are then expressed with#N#respect to the monics of generic Chu spaces, and universal, homogeneous Chu#N#spaces are shown to exist in this category. Unanticipated results driving this#N#development include the fact that while for generic Chu spaces monics consist#N#of an injective first and a surjective second component, in the extensional and#N#biextensional cases the surjectivity requirement can be dropped. Furthermore,#N#the desired colimits are only guaranteed to exist in the extensional case.#N#Finally, not all finite Chu spaces (considered set-theoretically) are finite#N#objects in their categories. This study opens up opportunities for further#N#investigations into recursively defined Chu spaces, as well as constructive#N#models of linear logic.
