A Variational Approach to Local Asymptotic and Exponential Stabilization of Nonlinear Systems
Bryce A. Christopherson, Farhad Jafari, Boris S. Mordukhovich
Local asymptotic stabilizability is a topic of great theoretical interest and practical importance. Broadly, if a system is locally asymptotically stabilizable,…
Modified Radon transform inversion using moments
H. Choi, V. Ginting, F. Jafari +1
Moment methods to reconstruct images from their Radon transforms are both natural and useful. They can be used to suppress noise or other spurious effects and can lead to highly ef…
Linear Openness and Feedback Stabilization of Nonlinear Control Systems
Rohit Gupta, Farhad Jafari, Robert J. Kipka +1
It is well known from the seminal Brockett's theorem that the openness property of the mapping on the right-hand side of a given nonlinear ODE control system is a necessary conditi…
Sparse Hamburger Moment Sequences and Completions in Several Variables
Saroj Aryal, Hayoung Choi, Farhad Jafari
Putinar and Vasilescu have given an algebraic characterization of Hamburger moment sequences in several variables. In this paper we give a characterization of sparse moment subsequ…
Hamburger moment sequences and their moment subsequences
Saroj Aryal, Hayoung Choi, Farhad Jafari
In this paper a connection between Hamburger moment sequences and their moment subsequences is given and the determinacy of these problems are related.
Modified Radon transform inversion using moments in
Hayoung Choi, Farhad Jafari, Robert Mnatsakanov
A modified Radon transform for noisy data is introduced and its inversion formula is established. The problem of recovering the multivariate probability density function from t…
Positive definite Hankel matrix completions and Hamburger moment completions
Hayoung Choi, Farhad Jafari
In this paper we give solutions to Hamburger moment problems with missing entries. The problem of completing partial positive sequences is considered. The main result is a characte…
Ellipsoidal cones in normed vector spaces
Farhad Jafari, Tyrrell B. McAllister
We give two characterizations of cones over ellipsoids in real normed vector spaces. Let be a closed convex cone with nonempty interior such that has a bounded section of c…
Characterization of Differentiable Copulas
Saikat Mukherjee, Farhad Jafari, Jong-Min Kim
This paper proposes a new class of copulas which characterize the set of all twice continuously differentiable copulas. We show that our proposed new class of copulas is a new gene…
Sparse Hamburger Moment Sequences
Saroj Aryal, Hayoung Choi, Farhad Jafari
Putinar and Vasilescu [6] have given an algebraic characterization of Hamburger moment sequences in several variables. In this paper we study some sparse moment subsequences of Ham…
On the range of composition operators on spaces of entire functions
S. Mukherjee, F. Jafari, J. E. McInroy
The celebrated Paley-Wiener theorem naturally identifies the spaces of bandlimited functions with subspaces of entire functions of exponential type. Recently, it has been shown tha…
