Abstract

Let (\mboxmodΛ,\mboxmodΛ,\mboxmodΛ)(\mbox{mod} \Lambda',\mbox{mod} \Lambda,\mbox{mod} \Lambda'') be a recollement of abelian categories for artin algebras Λ\Lambda', Λ\Lambda and Λ\Lambda''. Under certain conditions, we present an explicit construction of gluing of (support) τ\tau-tilting modules in \mboxmodΛ\mbox{mod} \Lambda with respect to (support) τ\tau-tilting modules in \mboxmodΛ\mbox{mod} \Lambda' and \mboxmodΛ\mbox{mod} \Lambda'' respectively; conversely, we study the construction of (support) τ\tau-tilting modules in \mboxmodΛ\mbox{mod} \Lambda' and \mboxmodΛ\mbox{mod} \Lambda'' obtained from (support) τ\tau-tilting modules in \mboxmodΛ\mbox{mod} \Lambda.
