Isomorphic copies of l_∞ in the weighted Hardy spaces on the unit disc. Radoslaw Szwedek, Adam Mickiewicz University, Poznan.

març 9, 2023 | Notícies, Seminari IUMPA

In this lecture, we shall discuss a question whether the density of analytic polynomials in an H-admissible space is sufficient to the minimality of the space? This question has a purely foundational background, relating fundamental concepts from the theory of Hp...

Linear dynamics of operators on non-metrizable topological vector spaces. Vinícius V. Fávaro, Universidade Federal de Uberlândia, Brasil.

març 8, 2023 | Notícies, Seminari IUMPA

In this talk we will explore the following notions of chaos for operators on non-metrizable topological vector spaces: mixing, hypercyclicity, cyclicity, n-supercyclicity, Li-Yorke chaos  and Devaney chaos. We will discuss the main differences between these...

Local Entropy and Applications. Udayan B. Darji, University of Louisville, EEUU.

març 7, 2023 | Notícies, Seminari IUMPA

In this talk, we introduce basic of local entropy theory and discuss how it can be applied in various settings in topological dynamics. We pay particular attention to Uniformly Positive Entropy and Complete Positive Entropy introduced by Blanchard in 90’s. Whereas...

The Perfekt theory of M-ideals. Dirk Werner, Freie Universität Berlin.

febr. 23, 2023 | Notícies, Seminari IUMPA

We revisit some ideas of K.-M. Perfekt who has provided an elegantframework to detect the biduality between function or sequence spacesdefined in terms of some o-resp.O-condition. We present new proofsunder somewhat weaker assumptions than before and apply the result...
