We address the invertibility problem for switched systems, which is the problem of recovering the switching signal and the input uniquely given an output and an initial state. In the context of hybrid systems, this corresponds to recovering the discrete state and the input from partial measurements of the continuous state. In solving the invertibility problem, we introduce the concept of singul...
We show that S.Vavasis’ sufficient condition for global invertibility of a polynomial mapping can be easily generalized to the case of a general Lipschitz mapping.
In this paper we characterize the boundedness and invertibility of composition operators on the space m(φ, p). Mathematics Subject Classification: Primary: 47B38, Secondary: 46A06
Necessary and sufficent conditions are obtained for ¿(/-factorization of operators on /,. In particular it is shown that uniform invertibility of the compressions of the operator is not sufficient to insure an LU-factorization of the operator, thus answering a question of de Boor, Jia, and Pinkus. The question of when a bounded linear operator on lp, 1 < p <, oo, has an Li/-factorization has be...
