The Expiring Coupon Collector: Sliding-Window Surjection Flux and Rare-Entry Laws

Christopher D. Long ยท 2026

We study the coupon collector with deterministic expiration: one coupon is drawn at each time, and each coupon remains active for exactly $M$ draws. Completion occurs when all $n$ coupon types are simโ€ฆ

Option-Order Randomisation Reveals a Distributional Position Attractor in Prompted Sandbagging

Jon-Paul Cacioli ยท 2026

A predecessor pilot (Cacioli, 2026) found that Llama-3-8B implements prompted sandbagging as positional collapse rather than answer avoidance. However, fixed option ordering in MMLU-Pro left open whetโ€ฆ

Adaptive Robust Confidence Intervals in Efron's Gaussian Two-Groups Model

Qiaosen Wang, Shuwen Chai, Chao Gao ยท 2026

Robust uncertainty quantification is increasingly important in modern data analysis and is often formalized under Huber's model, which allows an $\varepsilon$-fraction of arbitrary corruptions. In manโ€ฆ

Quantum Flat Connections, KZ equations, and Integrability

Sibasish Banerjee, Babak Haghighat, Anouchah Latifi ยท 2026

N=2 supyersymmetric Yang-Mills theories are described in terms of a Hitchin system over a Riemann surface C. Focusing on strongly coupled Argyres-Douglas theories, we show that the corresponding flat โ€ฆ
