The Codimension-Three conjecture for holonomic DQ-modules [PDF]
, 2014 We prove an analogue for holonomic DQ-modules of the codimension-three conjecture for microdifferential modules recently proved by Kashiwara and Vilonen.

Communications on Pure and Applied Mathematics, Volume 78, Issue 9, Page 1656-1702, September 2025.Abstract Let (Mn,g)$(M^n,g)$ be a complete Riemannian manifold which is not isometric to Rn$\mathbb {R}^n$, has nonnegative Ricci curvature, Euclidean volume growth, and quadratic Riemann curvature decay. We prove that there exists a set G⊂(0,∞)$\mathcal {G}\subset (0,\infty)$ with density 1 at infinity such that for every V∈G$V\in \mathcal {G}$ there ...

On the codimension of a minimal immersion [PDF]
Bulletin of the Australian Mathematical Society, 1984 We show that a certain local pinching condition on a compact minimal submanifold in a sphere leads to a condition on the codimension of the immersion.

Lie Flows of Codimension 3 [PDF]
Transactions of the American Mathematical Society, 1991 We study the following realization problem: given a Lie algebra of dimension 3 3 and an integer q , 0 ≤ q ≤ 3 q,0 \leq q \leq 3 , is there a compact manifold endowed with a Lie flow transversely modeled on G \mathcal {G} and with structural ...

Geometric realizations of the s‐weak order and its lattice quotients
Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.Abstract For an n$n$‐tuple s${\bm{s}}$ of nonnegative integers, the s${\bm{s}}$‐weak order is a lattice structure on s${\bm{s}}$‐trees, generalizing the weak order on permutations. We first describe the join irreducible elements, the canonical join representations, and the forcing order of the s${\bm{s}}$‐weak order in terms of combinatorial objects ...

Bifurcations of a Homoclinic Orbit to Saddle-Center in Reversible Systems
Abstract and Applied Analysis, 2012 The bifurcations near a primary homoclinic orbit to a saddle-center are investigated in a 4-dimensional reversible system. By establishing a new kind of local moving frame along the primary homoclinic orbit and using the Melnikov functions, the existence

Neighborhoods of Points in Codimension-One Submanifolds Lie in Codimension-One Spheres [PDF]
Proceedings of the American Mathematical Society, 1988 For n ≥ 4 n \geq 4 , let M M be an ( n − 1 ) (n - 1) -manifold embedded in an n n -manifold N N . For each point p p of M M , there is an ( n −

Decompositions into Codimension-Two Manifolds [PDF]
Transactions of the American Mathematical Society, 1985 Let M M denote an orientable ( n + 2 ) (n + 2) -manifold and let G G denote an upper semicontinuous decomposition of M M into continua having the shape of closed, orientable n n -manifolds.

Threshold Domain Sizes for Multifractality in Sea Ice Deformation
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract Sea ice dynamics has long been studied in both engineering and geophysical contexts, but unifying these scales remains elusive. Multifractality in ice deformation is a key metric for validating large‐scale continuum models. We perform a multifractal analysis on high‐resolution ship radar data over one winter.
