Positively Invariant Subset for Non-Densely Defined Cauchy Problems
Pierre Magal, Ousmane Seydi
In this article we prove the positive invariance of a closed subset by the semiflow generated by a semi-linear non densely Cauchy problem. The condition impose to obtain such a pro…

Monotone abstract non-densely defined Cauchy problems applied to age structured population dynamic models
Pierre Magal, Ousmane Seydi, Feng-Bin Wang
In this article we first derive some sufficient conditions to establish the monotonicity and comparison principles of the semi-flow generated by non-densely defined Cauchy problems…
