چکیده
V eronique Maume-Deschamps Section de Math ematiques, Universit e de Gen eve 2-4 rue du Lievre CP 240 Suisse. Abstract Let T be a measurable map on a Polish space X, let Y be a non trivial subset of X. We give conditions ensuring existence of conditionally invariant probability measures (to non absorption in Y). We also supply suucient conditions for these probability measures to be absolutely continuous with respect to some regular measure.

Metric Invariance Entropy and Conditionally Invariant Measures
A notion of metric invariance entropy is constructed with respect to a conditionally invariant measure for control systems in discrete time. It is shown that the metric invariance entropy is invariant under conjugacies, the power rule holds, and the (topological) invariance entropy provides an upper bound.

متن کاملLasota-yorke Maps with Holes: Conditionally Invariant Probability Measures and Invariant Probability Measures on the Survivor Set
Let T : I ?! I be a Lasota-Yorke map on the interval I, let Y be a non trivial sub-interval of I and g 0 : I ?! R + , be a strictly positive potential which belongs to BV and admits a conformal measure m. We give constructive conditions on Y ensuring the existence of absolutely continuous (w.r.t. m) conditionally invariant probability measures to non absorption in Y. These conditions imply also...
متن کاملEscape Rates and Conditionally Invariant Measures
We consider dynamical systems on domains that are not invariant under the dynamics – for example, a system with a hole in the phase space – and raise issues regarding the meaning of escape rates and conditionally invariant measures. Equating observable events with sets of positive Lebesgue measure, we are led quickly to conditionally invariant measures that are absolutely continuous with respec...
متن کاملInstitute for Mathematical Physics Conditionally Invariant Measures for Anosov Maps with Small Holes Conditionally Invariant Measures for Anosov Maps with Small Holes
We study Anosov diieomorphisms on surfaces in which some smalìholes' are cut. The points that are mapped into those holes disappear and never return. We assume that the holes are arbitrary open domains with piecewise smooth boundary, and their sizes are small enough. The set of points whose trajectories stay away from holes in the past is a Cantor-like union of unstable bers. We establish the e...
متن کاملMarkov extensions and conditionally invariant measures for certain logistic maps with small holes
We study the family of quadratic maps fa(x) = 1 − ax 2 on the interval [−1, 1] with 0 ≤ a ≤ 2. When small holes are introduced into the system, we prove the existence of an absolutely continuous conditionally invariant measure using the method of Markov extensions. The measure has a density which is bounded away from zero and is analogous to the density for the corresponding closed system. Thes...
