✍ Ruy Exel 📂 Article 📅 2000 🏛 Elsevier Science 🌐 English ⚖ 360 KB

Given a C\*-dynamical system (A, G, :), we discuss conditions under which subalgebras of the multiplier algebra M(A) consisting of fixed points for : are Morita Rieffel equivalent to ideals in the crossed product of A by G. In case G is abelian we also develop a spectral theory, giving a necessary a

✍ C. J. GOH; N. J. EDWARDS 📂 Article 📅 1997 🏛 John Wiley and Sons 🌐 English ⚖ 616 KB

We present a design methodology for the synthesis of a dynamic controller which minimizes an arbitrary performance index for a non-linear discrete-time system. We assume that only the output of the dynamical system is available for feedback. Consequently, the system input-output relation needs to be

We describe a class of measurable subsets \(\Omega\) in \(\mathbb{R}^{d}\) such that \(L^{2}(\Omega)\) has an orthogonal basis of frequencies \(e_{\lambda}(x)=e^{i 2 \pi \lambda \cdot x}(x \in \Omega)\) indexed by \(\lambda \in A \subset \mathbb{R}^{d}\). We show that such spectral pairs \((\Omega,
