PREPRINT ANNOUNCEMENT

Algebraic theories in monoidal categories
Luca Mauri

Abstract. We define a monoidal semantics for algebraic theories. The basis for
the definition is provided by the analysis of the structural rules in the
term calculus of algebraic languages. Models are described both explicitly,
in a form that generalises the usual definition in sets; and from a
category-theoretical point of view, as monoidal functors on suitable
classifying categories. The semantics obtained includes as special cases both
the semantics of ordinary algebraic theories in Cartesian categories, and the
semantics of operads and multicategories over sets.

The article is in PDF format (~250 KB, 26 pages) and can be be downloaded
