Abstract

Let (A, B, C, i*, i, i!,j_!, j^∗, j_∗) be a recollement of extriangulated categories. We show that there is a bijection between thick subcategories in C and thick subcategories in B containing iA. Futhermore, the thick subcategories V in B containing iA can induce a new recollement relative to A and jV. We also prove that silting subcategories in A and C can be glued to get silting subcategories in B and the converse holds under certain conditions.
