Title: Computads and slices of operads Authors: M.A.Batanin Comments: 18 pages Subj-class: Category Theory MSC-class: 18C20, 18D05 \\ For a given $\omega$-operad $A$ on globular sets we introduce a sequence of symmetric operads on $Set$ called slices of $A$ and show how the connected limit preserving properties of slices are related to the property of the category of $n$-computads of $A$ being a presheaf topos. \\
