Skein Relations in Punctured Surface Cluster Algebras

Published:Dec 30, 2025 20:01
1 min read
ArXiv

Analysis

This paper extends the study of cluster algebras, specifically focusing on those arising from punctured surfaces. It introduces new skein-type identities that relate cluster variables associated with incompatible curves to those associated with compatible arcs. This is significant because it provides a combinatorial-algebraic framework for understanding the structure of these algebras and allows for the construction of bases with desirable properties like positivity and compatibility. The inclusion of punctures in the interior of the surface broadens the scope of existing research.
Reference

“The paper introduces skein-type identities expressing cluster variables associated with incompatible curves on a surface in terms of cluster variables corresponding to compatible arcs.”

Antarctic Sky Survey: Data Reduction and Preliminary Results

Published:Dec 30, 2025 08:23
1 min read
ArXiv

Analysis

This paper details the data reduction pipeline and initial results from the Antarctic TianMu Staring Observation Program, a time-domain optical sky survey. The project leverages the unique observing conditions of Antarctica for high-cadence sky surveys. The paper's significance lies in demonstrating the feasibility and performance of the prototype telescope, providing valuable data products (reduced images and a photometric catalog) and establishing a baseline for future research in time-domain astronomy. The successful deployment and operation of the telescope in a challenging environment like Antarctica is a key achievement.
Reference

“The astrometric precision is better than approximately 2 arcseconds, and the detection limit in the G-band is achieved at 15.00~mag for a 30-second exposure.”

Helical Fermi Arc in Altermagnetic Weyl Semimetal

Published:Dec 30, 2025 01:28
1 min read
ArXiv

Analysis

This paper introduces a novel mechanism for realizing altermagnetic Weyl semimetals, a new type of material with unique topological properties. The authors explore how an altermagnetic mass term can drive transitions between different Chern phases, leading to the creation of helical Fermi arcs. This work is significant because it expands our understanding of Dirac systems and provides a pathway for experimental realization of these materials.
Reference

“The paper highlights the creation of coexisting helical Fermi arcs with opposite chirality on the same surface, a phenomenon not found in conventional magnetic Weyl semimetals.”
