Abstract

Let (\mboxmodΛ,\mboxmodΛ,\mboxmodΛ)(\mbox{mod} \Lambda',\mbox{mod} \Lambda,\mbox{mod} \Lambda'') be a recollement of module categories for artin algebras Λ\Lambda', Λ\Lambda and Λ\Lambda''. We provide a sufficient condition such that a glued torsion pair in \mboxmodΛ\mbox{mod} \Lambda is tilting when the given two torsion pairs are tilting in \mboxmodΛ\mbox{mod} \Lambda' and \mboxmodΛ\mbox{mod} \Lambda'' respectively. Using this result, we give a construction of gluing of tilting modules in \mboxmodΛ\mbox{mod} \Lambda with respect to tilting modules in \mboxmodΛ\mbox{mod} \Lambda' and \mboxmodΛ\mbox{mod} \Lambda'' respectively.
