Realizing Arbitrary Depth
Ethan Akin
We provide a simple construction which realizes the Birkhoff center depth at an arbitrary ordinal level and relate it to the Cantor-Bendixson depth.
Invertibility, Often
Ethan Akin, Benjamin Weiss
By using a similar pattern of arguments, we show that in four categories the collection of isomorphisms forms a residual subset of the space of morphisms. We first consider surject…
A Complete Invariant for Shift Equivalence for Boolean Matrices and Finite Relations
Ethan Akin, Marian Mrozek, Mateusz Przybylski +1
We give a complete invariant for shift equivalence for Boolean matrices (equivalently finite relations), in terms of the period, the induced partial order on recurrent components,…
The Simple Yield Curve Models
Ethan Akin, Morton Davis
With the price in current dollars of a dollar delivered time units from now, we assume that is a decreasing function defined for with .…
Conditional cooperation with longer memory
Nikoleta E. Glynatsi, Martin A. Nowak, Christian Hilbe
Direct reciprocity is a wide-spread mechanism for evolution of cooperation. In repeated interactions, players can condition their behavior on previous outcomes. A well known approa…
Dynamical Systems: Discrete, Continuous and Hybrid
Ethan Akin
The dynamics by iteration of a function on a compact metric space, sometimes called a cascade, can be extended to the dynamics of a closed relation on such a space. Here we apply t…
