Functoriality of the Klein-Williams Invariant and Universality Theory
Both the Klein-Williams invariant $\ell_G(f)$ from \cite{KW2} and the generalized equivariant Lefschetz invariant $λ_G(f)$ from \cite{weber07} serve as complete obstructions to the fixed point problem in the equivariant setting. The latter is functorial in the sense of Definition \ref{functorial}. The first part of this paper aims to demonstrate that $\ell_G(f)$ is also functorial. The second part summarizes the ``universality" theory of such functorial invariants, developed in \cites{lueck199…

Intraday Functional PCA Forecasting of Cryptocurrency Returns
We study the Functional PCA (FPCA) forecasting method in application to functions of intraday returns on Bitcoin. We show that improved interval forecasts of future return functions are obtained when the conditional heteroscedasticity of return functions is taken into account. The Karhunen-Loeve (KL) dynamic factor model is introduced to bridge the functional and discrete time dynamic models. It offers a convenient framework for functional time series analysis. For intraday forecasting, we intr…

Anyway, you seem to be missing my point, and it’s starting to feel like it’s on purpose.

From learnable objects to learnable random objects
We consider the relationship between learnability of a "base class" of functions on a set $X$, and learnability of a class of statistical functions derived from the base class. For example, we refine results showing that learnability of a family $h_p: p \in Y$ of functions implies learnability of the family of functions $h_μ=λp: Y. E_μ(h_p)$, where $E_μ$ is the expectation with respect to $μ$, and $μ$ ranges over probability distributions on $X$. We will look at both Probably Approximatel…

Audio-Mix-Funktion nicht mehr nur für Apples eigene Apps
Apple erlaubt es bei der Wiedergabe mit seiner Fotos-App, verschiedene Mikrofon-Klangmodelle zu nutzen. Das kommt mit iOS 26 auch für Third-Party-Anwendungen.

Apples Einladungen-App mit erstem Feature-Update
Die seit Februar erhältliche Apple-App zur Verwaltung von Events auf dem iPhone bekommt neue Funktionen. Bislang aktualisierte der Konzern nur sparsam.

Pro & Contra: Brauchen wir ein Bugfix-macOS?
Redesign-Gerüchte sorgen bei manchen für Augenrollen. Statt neuer Funktionen wünschen sie sich mehr Stabilität. Muss Apple auf die Feature-Bremse treten?
