On reachability and controllability for a Volterra integro-dynamic system on time scales

open access: yes
The paper studies and relates the notions of reachability and controllability for the Volterra integro-dynamic system on time scales. More specifically, we obtain necessary and sufficient conditions for reachability and controllability.

CONTROL NORMS FOR LARGE CONTROL TIMES

open access: yes, 1998
. A control system of the second order in time with control u = u(t) 2 L2([0; T];U) is considered. If the system is controllable in a strong sense and uT is the control steering the system to the rest at time T, then the L2{norm of uT decreases as 1= p T

Existence of solutions for fractional Choquard-Kirchhoff type problems with critical growth

open access: yes四川大学学报. 自然科学版
In this paper, the fractional Choquard-Kirchhoff type problems on unbounded domains are considered.These problems stem from the tension arising from nonlocal measurements of length of a string during transverse vibration and can also be used to describe ...
