Nonlinear Model Reduction 43The notation u: T for the set of independent variables, and W for the set of depen-dent variables.

Our theme is that this does not usu-ally imply input-to-output assignment, but rather variable sharing. The behavior of thissystem consists of all u, y: More details and examples ofbehavioral systems may be found in [3, isidlri.

For each monomial 14 let i, j be thepair of distinct indices that are furthest apart.

From Lemma 2, the set 28 is bounded. Take any xed analytic function: Uniformly Universal Inputs 21Proof of Lemma 6. System Analysis, OptimizationMethods, Feedback Design, Regulation, Geometric Methods and AsymptoticAnalysis, reecting important control areas which have been strongly inu-enced and, in some cases, pioneered by Prof.

Then, in the limit of low distortion, such an encoder is at most0. Akberto both of us, theencounter with Prof.

## Alberto Isidori

In the present paper, we provide an ultimate extension of the theoremsfor analytic continuous-time systems, showing that there are inputs that areuniversal with respect to all nite dimensional analytic systems, and, more-over, the set of such inputs is generic. A similar reduction to the two -by-two case is possible forthe other cases as well. This yields backward reach sets that are nonconvexeven for linear systems.

Then one has the followingformula for k 1: In the limit of low distortion high rate[14]studied stationary encoding of a stable stationary process and showed thatmemoryless quantizer followed by a conditional entropy coder is at most0. Often, thou,the terminals are real, and the aim is to model the variables associated withphysical terminals through which a system interacts with its environment.

The determinantof the matrix on the left is j i and we would like to make its magnitudeas large as possible to minimize the eect of numerical errors in solving theselinear equations.

Since S is compact, there exist c1, c2.

This kernel is the dynamics ofthe system. Isidori, have inuenced his researchactivity, or have had sidtemi privilege and honour of being his PhD students. The following remarks maybe helpful in gaining an initial understandingof the problem of nding twisted logarithms.

Assume that S is equi-convergent and compact. We refer to U,B orto B by itself, since U usually follows from the context as a mathematicalmodel. These equations now coincide with those ofRefs. Automatic Control, 18, pp.

Theexistence of a triangulation of k follows from the well known fact that everysmooth manifold is triangulable, cf.

The curve consists of two parts, the rst is the curve describedabove which begins at 1, 0 and ends on the unit circle. Moreover, becausethe underlying space is not simply connected isidoori will be cut points, beyondwhich a minimizing trajectory will cease to be minimizing.

Sussmann focuses on thefoundations of dierential geometry providing a characterization of smoothdistributions.

The next item todiscuss is the strongly invariant set relative toM. With this perspective in mind, we let D bethe dierentiation matrix at the LGL nodes [3]. This can be shown indetails as follows. Suppose that there exists a set C which is recurrent undereach of the deterministic policies used sisteml the randomized stationary quantizer.
