Conformal surface defects in Maxwell theory are trivial
Journal of High Energy Physics, 2022 We consider a free Maxwell field in four dimensions in the presence of a codimension two defect. Reflection positive, codimension two defects which preserve conformal symmetry in this context are very limited.

Codimension two holomorphic foliation
Journal of Differential Geometry, 2019 This paper is devoted to the study of codimension two holomorphic foliations and distributions. We prove the stability of complete intersection of codimension two distributions and foliations in the local case. Converserly we show the existence of codimension two foliations which are not contained in any codimension one foliation.

Codimension-Two Bifurcations of Fixed Points in a Class of Discrete Prey-Predator Systems
Discrete Dynamics in Nature and Society, 2011 The dynamic behaviour of a Lotka-Volterra system, described by a planar map, is analytically and numerically investigated. We derive analytical conditions for stability and bifurcation of the fixed points of the system and compute analytically the normal

Embedding codimension of the space of arcs
Forum of Mathematics, Pi, 2022 We introduce a notion of embedding codimension of an arbitrary local ring, establish some general properties and study in detail the case of arc spaces of schemes of finite type over a field.

The consistency of codimension-2 braneworlds and their cosmology [PDF]
, 2009 We study axially symmetric codimension-2 cosmology for a distributional braneworld fueled by a localised 4D perfect fluid, in a 6D Lovelock theory. We argue that only the matching conditions (dubbed topological) where the extrinsic curvature on the brane

BRANE INDUCED GRAVITY: CODIMENSION-2 [PDF]
Modern Physics Letters A, 2008 We review the results of arXiv:hep-th/0703190, on brane induced gravity (BIG) in 6D. Among a large diversity of regulated codimension-2 branes, we find that for near-critical tension branes live inside very deep throats which efficiently compactify the angular dimension. In there, 4D gravity first changes to 5D, and only later to 6D.

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 ...

Proximinality in generalized direct sums
International Journal of Mathematics and Mathematical Sciences, 2004 We consider proximinality and transitivity of proximinality for subspaces of finite codimension in generalized direct sums of Banach spaces. We give several examples of Banach spaces where proximinality is transitive among subspaces of finite codimension.

Bifurcations of piecewise smooth flows:perspectives, methodologies and open problems [PDF]
, 2012 In this paper, the theory of bifurcations in piecewise smooth flows is critically surveyed. The focus is on results that hold in arbitrarily (but finitely) many dimensions, highlighting significant areas where a detailed understanding is presently ...

, 2013 We show that all finite-dimensional resolvable generalized manifolds with the piecewise disjoint arc-disk property are codimension one manifold factors. We then show how the piecewise disjoint arc-disk property and other general position properties that ...
