DOI: 10.1002/mma.6865

Abstract: This research work is related to investigate sufficient conditions for existence, uniquely of solution to a coupled system of nonlinear fractional order hybrid differential equations (NFOHDEs). With the help of Burton's fixed point theorem, we… read more here.

DOI: 10.1007/s00373-017-1873-5

Abstract: In this paper, we survey results and conjectures on degree conditions for the existence of vertex-disjoint cycles and paths. In particular, we focus on the type of degree conditions, the type of cycles or paths,… read more here.

DOI: 10.1007/s10958-017-3299-2

Abstract: We consider a class of problems of optimal control on finite and infinite time scales. For these problems, we establish sufficient conditions for the existence of optimal control formulated in terms of the right-hand sides… read more here.

DOI: 10.1080/09720502.2020.1800226

Abstract: Abstract This paper investigates the existence of solutions for a boundary value problem of Hadamard fractional differential equations with nonlocal conditions. The existence and uniqueness of solutions is derived from Banach’s contraction principle. Then, by… read more here.

DOI: 10.1109/tac.2018.2868239

Abstract: For linear discrete state-space models, under certain conditions, the linear least mean squares (LLMS) filter estimate has a recursive format, a.k.a. the Kalman filter (KF). Interestingly, the linear minimum variance distortionless response (LMVDR) filter, when… read more here.
