| contents | In this paper we introduce the notion of a relative volutive (higher) category, specializing to the notion of a lax volutive (higher) category. Our primary motivation to study these objects is the following: while any rigid symmetric monoidal category admits a volutive structure, any closed symmetric monoidal category admits a lax volutive structure. We develop some of the basic theory of relative volutive categories and provide several equivalent formulations of lax volutive categories. We then study examples of interest, including categories of complete bornological vector spaces and modules over star-rings. We will also separately discuss unbounded operators between Hilbert spaces and Morita 2-categories, the latter of which in the context of fully closed symmetric monoidal 2-categories. |
