Abstract

We prove some general results on sequential convergence in Fréchet lattices that yield, as particular instances, the following results regarding a closed ideal

I

of a Banach lattice

E

: (i) If two of the lattices

E

I

and

E / I

have the positive Schur property (the Schur property, respectively) then the third lattice has the positive Schur property (the Schur property, respectively) as well; (ii) If

I

and

E / I

have the dual positive Schur property, then

E

also has this property; (iii) If

I

has the weak Dunford-Pettis property and

E / I

has the positive Schur property, then

E

has the weak Dunford-Pettis property. Examples and applications are provided.
