A colimit decomposition for the loop homology of polyhedral products

Lewis Stanton, Fedor Vylegzhanin · 2026

We show that the loop homology algebras of polyhedral products of the form $(\underline{X},\underline{*})^{\mathcal{K}}$ can be written as a colimit over the flagification of $\mathcal{K}$, and obtain…

ValueAlpha: Agreement-Gated Stress Testing of LLM-Judged Investment Rationales Before Returns Are Observable

Sidi Chang, Peiying Zhu, Yuxiao Chen · 2026

Long-horizon investment decisions create a pre-realization evaluation problem: realized returns are the eventual arbiter of investment quality, but they arrive too late and are too noisy to guide many…

RefEvo: Agentic Design with Co-Evolutionary Verification for Agile Reference Model Generation

Yifan Zhang, Jianmin Ye, Jiahao Yang, Xi Wang · 2026

As the complexity of System-on-Chip (SoC) designs grows, the shift-left paradigm necessitates the rapid development of high-fidelity reference models (typically written in SystemC) for early architect…

Sharp pathwise nonuniqueness for additive SDEs

Elias Hess-Childs, Keefer Rowan · 2026

We construct a family of velocity fields demonstrating the sharpness of the classical Zvonkin--Veretennikov--Davie strong well-posedness by noise regime. We consider stochastic differential equations …

Benchmarking Open-Source FDK Against Commercial and Iterative Reconstruction Methods for Preclinical Micro-CBCT

Falk L Wiegmann, Nancy L Ford · 2026

Preclinical micro-CT reconstruction involves large projection sizes and volumes that make iterative methods costly - 5x to 50x slower than analytic alternatives on modern GPUs. Whether this cost is ju…

Meshless $h$-adaptive Solution for non-Newtonian Natural Convection in a Differentially Heated Cavity

Miha Rot, Gregor Kosec · 2026

One of the main challenges in numerically solving partial differential equations is finding a discretisation for the computational domain that balances the accurate representation of the underlying fi…

Spectral Embeddings Leak Graph Topology: Theory, Benchmark, and Adaptive Reconstruction

Thinh Nguyen-Cong, Truong-Son Hy, Thang N. Dinh · 2026

Graph Neural Networks (GNNs) excel on relational data, but standard benchmarks unrealistically assume the graph is centrally available. In practice, settings such as Federated Graph Learning, distribu…

The Steklov spectrum of convex polygonal domains II: investigating spectral determination

Emily B. Dryden, Carolyn Gordon, Javier Moreno, Julie Rowlett, Carlos Villegas-Blas · 2026

The extent to which the geometry of an object is determined by some associated spectral data is a longstanding problem. We investigate this problem in the context of the Steklov spectrum, focusing on …

Contagion or Macroeconomic Fluctuations? Identifiability in Aggregated Default Data

Shintaro Mori · 2026

Can contagion be inferred from aggregated default data? We study this as a problem of identifiability, asking whether contagion generates components in default count distributions that remain distinct…

From Craft to Kernel: A Governance-First Execution Architecture and Semantic ISA for Agentic Computers

Xiangyu Wen, Yuang Zhao, Xiaoyu Xu, Lingjun Chen, Changran Xu, Shu Chi, Jianrong Ding, Zeju Li, Haomin Li, Li Jiang, Fangxin Liu, Qiang Xu · 2026

The transition of agentic AI from brittle prototypes to production systems is stalled by a pervasive crisis of craft. We suggest that the prevailing orchestration paradigm-delegating the system contro…

Extrapolation of max-stable random fields with Fr\'echet marginals

Vitalii Makogin, Evgeny Spodarev, Ilja Sukhanov · 2026

We propose a method for the prediction of stationary max--stable random fields with $\alpha$-Fr\'echet marginal distribution $H_\alpha$. The method is suitable to cope with heavy tails for $\alpha\in(…

Algebraic redshift in the $C_2$-equivariant Adams spectral sequence

Paul Shick · 2026

We study $v_n$-periodic phenomena in $C_2$-equivariant stable homotopy through the lens of the $C_2$-equivariant Adams spectral sequence at the prime 2. In particular, we construct/detect certain clas…
