Algorithms of the Möbius function by random forests and neural networks

Journal of Big Data
The Möbius function $$\mu (n)$$ μ ( n ) is known for containing limited information on the prime factorization of n. Its known algorithms, however, are all based on factorization and hence are exponentially slow on $$\log n$$ log n .

On the structure of higher order quantum maps [PDF]

Quantum
We study higher order quantum maps in the context of a *-autonomous category of affine subspaces. We show that types of higher order maps can be identified with certain Boolean functions that we call type functions. By an extension of this identification,

Short‐Term Complications Are Rare After Cholesteatoma Surgery

Clinical Otolaryngology, Volume 51, Issue 5, Page 660-665, September 2026.
ABSTRACT Objective To evaluate the incidence and nature of short‐term complications following cholesteatoma surgery in a heterogeneous cohort. Design A retrospective cohort study including complete coverage of cholesteatoma surgery in a Swedish region between 1 January 2005 and 31 December 2015.

Holographic Weyl anomaly in string theory

SciPost Physics
We compute the worldsheet sphere partition function of string theory on global AdS$_3$ with pure NS-NS flux. Because of an unfixed Möbius symmetry on the worldsheet, there is a cancellation of infinities and only a part of the answer is unambiguous.

Inductive Differential Constraint Method: Symbolic Regression‐Based Partial Differential Equation Regularization for Fatigue Crack Growth Prediction

International Journal for Numerical Methods in Engineering, Volume 127, Issue 15, 15 August 2026.
ABSTRACT This study introduces the inductive differential constraint method (IDCM), a data‐informed structural regularization framework that enhances neural network predictions under data‐scarce regimes by enforcing invariant differential structures extracted from simulation data.

Initial experience of clinical implementation of an Online Simulation‐free CBCT‐based Adaptive Radiotherapy (OSCAR) workflow for palliative and urgent treatment indications

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background The current standard radiotherapy treatment planning workflow typically requires several hours to days, during which patients must wait before treatment can be initiated. In certain oncological situations, however, treatment should commence as soon as possible.

Gyronormed Function Spaces [PDF]

Mathematics Interdisciplinary Research
‎In this paper‎, ‎we introduce a gyrodistance on the gyrolinear space of functions (whose gyronorm is measurable) from a measure space to the Möbius disk $\mathbb{D}$‎.

Asymmetric Results About Graph Homomorphisms

Random Structures &Algorithms, Volume 69, Issue 1, August 2026.
ABSTRACT Many important results in extremal graph theory can be roughly summarized as “if a triangle‐free graph G$$ G $$ has certain properties, then it has a homomorphism to a triangle‐free graph Γ$$ \Gamma $$ of bounded size.” For example, bounds on homomorphism thresholds give such a statement if G$$ G $$ has sufficiently high minimum degree, and ...

Totally elliptic surface group representations

Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract A surface group representation into a Lie group is totally elliptic if every simple closed curve on the surface is mapped to an elliptic element. In this note, we characterize all totally elliptic surface group representations into PSL2R$\operatorname{PSL}_2 \mathbb {R}$ and PSL2C$\operatorname{PSL}_2\mathbb {C}$ by showing that they are ...
