ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 10, October 2025.Abstract We examine pairs of closed plane curves that have the same closing property as two conic sections in Poncelet's porism. We show how the vertex curve can be computed for a given envelope and vice versa. Our formulas are universal in the sense that they produce all possible sufficiently regular pairs of such Poncelet curves. We arrive at similar

Rigid circle domains with non‐removable boundaries
Proceedings of the London Mathematical Society, Volume 131, Issue 3, September 2025.Abstract We give a negative answer to the rigidity conjecture of He and Schramm by constructing a rigid circle domain Ω$\Omega$ on the Riemann sphere Ĉ$\hat{\mathbb {C}}$ with conformally non‐removable boundary. Here, rigidity means that every conformal map from Ω$\Omega$ onto another circle domain is a Möbius transformation, and non‐removability ...

Continuity of HYM connections with respect to metric variations
Journal of the London Mathematical Society, Volume 112, Issue 1, July 2025.Abstract We investigate the set of (real Dolbeault classes of) balanced metrics Θ$\Theta$ on a balanced manifold X$X$ with respect to which a torsion‐free coherent sheaf E$\mathcal {E}$ on X$X$ is slope stable. We prove that the set of all such [Θ]∈Hn−1,n−1(X,R)$[\Theta] \in H^{n - 1,n - 1}(X,\mathbb {R})$ is an open convex cone locally defined by a ...

Finite Minkowski planes of type 20 with respect to homotheties
Finite Fields and Their Applications, 2016 In [J. Geom. 43, No. 1--2, 116--128 (1992; Zbl 0746.51009)], \textit{M. Klein} classified Minkowski planes with respect to \(\{p,p'\}\)-homotheties. If \({\mathcal M}\) is a Minkowski plane and \(p\) and \(p'\) are non-parallel points of \({\mathcal M}\), then a \(\{p,p'\}\)-homothety is an automorphism of \({\mathcal M}\) fixing both \(p\) and \(p ...

Transformations and Preservation of Self-assembly Dynamics through Homotheties [PDF]
, 2008 We introduce a new notion in self-assembly, that of transforming the dynamics of assembly. This notion allows us to have transformation of the plane computed within the assembly process. Then we apply this notion to zooming. The possibility of zooming depends on the order condition. This shows that this condition, which arose from engineering concerns (
