Resumen de Delay independent stability for some partial functional differential equations with infinite delay under the light of positivity

Khalil Ezzinbi, Soumia Lalaoui Rhali

• In this work, we deal with the positivity and stability study for some partial functional differential equations with infinite delay and Hille–Yosida operators. We first show the positivity of solutions in a suitable phase space. This enables us to establish a stability criterion independently of delay.
