Maximum in-general-position set in a random subset of $\mathbb{F}^d_q$ Open
Let $α(\mathbb{F}_q^{d},p)$ be the maximum possible size of a point set in general position in a $p$-random subset of $\mathbb{F}_q^d$. We determine the order of magnitude of $α(\mathbb{F}_q^{d},p)$ up to a polylogarithmic factor by provin…

Limit for Quotient Convergent Graph Sequence Open
Building on the limit theory for set functions, we prove that the limit of convergent sequence of bounded-degree graphs' cycle matroids can be represented as the cycle matroid of a graphing, analogous to the completeness result for local-g…

Hausdorff Distance-based Tool Position Planning Method for Plunge Milling of 3D Impeller Channels in Shroud-enabled Blade Milling Open
In the context of plunge milling for rough-machined three-dimensional (3D) impeller channels using the shroud-enabled blade milling method, substantial non-uniform allowances often persist on the inner surface of the shroud. To address thi…

Embedding loose trees in $k$-uniform hypergraphs Open
A classical result of Komlós, Sárközy and Szemerédi shows that every large $n$-vertex graph with minimum degree at least $(1/2+γ)n$ contains all spanning trees of bounded degree. We generalised this result to loose spanning hypertrees in $…
