Time-discretization method for a multi-term time fractional differential equation with delay
Areefa Khatoon, Abdur Raheem, Asma Afreen
This paper discusses a multi-term time-fractional delay differential equation in a real Hilbert space. An iterative scheme for a multi-term time-fractional differential equation is…
Stochastic controllability for a non-autonomous fractional neutral differential equation with infinite delay in abstract space
Areefa Khatoon, Abdur Raheem, Asma Afreen
This paper deals with the controllability for a class of non-autonomous neutral differential equations of fractional order with infinite delay in an abstract space. The semi-group…
Controllability of a second-order impulsive neutral differential equation via resolvent operator technique
Asma Afreen, Abdur Raheem, Areefa Khatoon
This paper uses the resolvent operator technique to investigate second-order non-autonomous neutral integrodifferential equations with impulsive conditions in a Banach space. We st…
Optimal controllability for multi-term time-fractional stochastic systems with non-instantaneous impulses
Asma Afreen, Abdur Raheem, Areefa Khatoon
In the present paper, we study the existence and optimal controllability of a multi-term time-fractional stochastic system with non-instantaneous impulses. Using semigroup theory,…
A study of nonlocal fractional neutral stochastic integrodifferential inclusions of order with impulses
Asma Afreen, Abdur Raheem, Areefa Khatoon
This paper considers a class of nonlocal fractional neutral stochastic integrodifferential inclusions of order with impulses in a Hilbert space. We study the existence of t…
