Construct ideal cotorsion pairs by recollement of triangulated categories
Let $(\mathcal{T}',\mathcal{T},\mathcal{T}'')$ be a recollement of
triangulated categories. Two complete ideal cotorsion pairs in $\mathcal{T}'$
and $\mathcal{T}''$ can be induced by a complete ideal cotorsion pair in
$\mathcal{T}$. If $(\mathcal{I},\mathcal{I}^\perp )$ and
$(\mathcal{J},\mathcal{J}^\perp)$ are two complete ideal cotorsion pair in
triangulated category, then
$(\mathcal{I}\cap\mathcal{J},\langle\mathcal{I}^\perp,\mathcal{J}^\perp\rangle)$
is also a complete ideal cotorsion pair. In this way, a series of ideal
cotorsion pairs in $\mathcal{T}$ can be induced by two ideal cotorsion pairs in
$\mathcal{T}'$ and $\mathcal{T}''$.
