The C-index Multiverse
Quantifying out-of-sample discrimination performance for time-to-event outcomes is a fundamental step for model evaluation and selection in the context of predictive modelling. The concordance index, or C-index, is a widely used metric for this purpose, particularly with the growing development of machine learning methods. Beyond differences between proposed C-index estimators (e.g. Harrell's, Uno's and Antolini's), we demonstrate the existence of a C-index multiverse among available R and pyth…

MIO: Multiverse Debugging in the Face of Input/Output -- Extended Version with Additional Appendices
Debugging non-deterministic programs on microcontrollers is notoriously challenging, especially when bugs manifest in unpredictable, input-dependent execution paths. A recent approach, called multiverse debugging, makes it easier to debug non-deterministic programs by allowing programmers to explore all potential execution paths. Current multiverse debuggers enable both forward and backward traversal of program paths, and some facilitate jumping to any previously visited states, potentially bra…

Multiverse Predictions for Habitability: Fundamental Physics and Galactic Habitability
In the multiverse hypothesis, a range of universes exist with differing values of our physical constants. Here, we investigate how the probabilities of observing our values of these constants depend on the assumptions made about the theories governing particle physics and cosmology, along with habitability. The particle physics effects we consider include constraints on the Higgs vacuum expectation value from big bang nucleosynthesis and supernovae, grand unified theories (GUTs), and standard m…

Modeling in the Design Multiverse
Real-world design processes often involve the evolution and divergence of design paths (by branching, revising, merging, etc.), especially when multiple stakeholders or teams operate concurrently and/or explore different alternatives for complex and heterogeneous systems. Unfortunately, this variability in time and space can not be directly managed in current modeling spaces but requires resorting to external tools and methodologies. In order to tackle this problem, we introduce the Design Mu…

Internal Categoricity and the Generic Multiverse
John Steel's theory, MV, of the generic multiverse provides a foundation for mathematics that aims to neutralize the effects of incompleteness brought on by forcing arguments. Jouko Väänänen's development of internal categoricity arguments provides opportunities to argue that the subject matter of some theory is, in some sense, determined. This paper investigates whether MV is internally categorical.

Somewhere out there in the multiverse, there's a version of earth where it wasn't John Mastodon who wrote the most popular activitypub-using social networking site, but rather some guy named Fred.
The frediverse is real popular over there, with almost half a billion people on fredi.

Total instanton restriction via multiverse interference: Noncompact gauge theories and (-1)-form symmetries

Total instanton restriction via multiverse interference: Noncompact gauge theories and (-1)-form symmetries
In this note we consider examples of decomposition (in which a local QFT is equivalent to a disjoint union of multiple independent theories, known as universes) where there is a continuous familiy of universes, rather than a finite or countably infinite collection. In particular, this allows us to consistently eliminate all instantons in a local QFT via a suitable topological gauging of the (-1)-form symmetry. In two-dimensional U(1) gauge theories, this is equivalent to changing the gauge gruo…

Holistic Versus Fragmented Multiverses: Empirical Access via Causal and Grounding Signatures
Can multiverse hypotheses ever receive empirical support? Critics argue that multiverse scenarios posit unobservable entities, face severe underdetermination, or fall outside the bounds of science. This chapter challenges that view by offering a naturalistic metaphysical counterpoint to Bayesian approaches, distinguishing fragmented from holistic multiverses. Scientific proposals are almost always holistic: they embed universes within a unifying physical or metaphysical structure that can, in p…
