Finite group actions on genus two SL(2,C)SL(2, \mathbb{C})-character variety and applications to SCFTs

This paper investigates the irreducible components of fixed point sets within the SL(2,C)SL(2, \mathbb{C})-character variety of a genus two surface under finite group actions, utilizing the genus two DAHA to identify geometric transitions that yield novel candidates for symmetry-reduced moduli spaces in 4d N=2\mathcal{N}=2 SCFTs.

Hard/Soft NLoS Detection via Combinatorial Data Augmentation for 6G Positioning

This paper proposes the combinatorial data augmentation-guided NLoS detection (CDA-ND) algorithm, which generates NLoS evidence vectors from multilateration-based location clusters to enable both hard and soft NLoS detection modes, significantly improving 6G positioning accuracy in indoor factory environments by reducing mean absolute error by up to 66%.

A note on small cap square function and decoupling estimates for the parabola

This paper establishes sharp, up to polylogarithmic factors, small cap square function and decoupling estimates for the parabola using axis-parallel rectangles of dimensions δ×δβ\delta \times \delta^\beta for $0 \leq \beta \leq 1,therebycomplementingexistingresultsfortherange, thereby complementing existing results for the range 1 \leq \beta \leq 2$.
