Hodge theory of abelian covers of algebraic varieties
Forum of Mathematics, SigmaMotivated by classical Alexander invariants of affine hypersurface complements, we endow certain finite dimensional quotients of the homology of abelian covers of complex algebraic varieties with a canonical and functorial mixed Hodge structure (MHS ...

Pinwheels in symplectic rational and ruled surfaces and non‐squeezing of rational homology balls
Journal of Topology, Volume 19, Issue 3, September 2026.Abstract We use almost toric fibrations and the symplectic rational blow‐up to determine when certain Lagrangian pinwheels, which we call liminal, embed in symplectic rational and ruled surfaces. The case of L2,1$L_{2,1}$‐pinwheels, namely Lagrangian RP2s$\mathbb {R}P^2{\rm s}$, answers a question of Kronheimer in the negative, exhibiting a symplectic ...

Simple homotopy theory for Fukaya categories
Journal of Topology, Volume 19, Issue 3, September 2026.Abstract We develop a categorical framework for simple homotopy theory in Fukaya categories, based on the fundamental group of the ambient symplectic manifold. When the first Chern class vanishes, we show that any isomorphism in the Fukaya category of a Weinstein manifold has trivial Whitehead torsion.

, 1999 We show that any knot or link can arise as the real part of the Milnor fibre in a flat deformation of an appropriate space curve singularity.

A Formula Similar to a Consequence of the Join Theorem
AxiomsLet u:(Cm,0)→(C,0) and v:(Cn,0)→(C,0) be holomorphic function germs that have isolated critical points at the origin. It is known that μ(u+v)=μ(u)·μ(v) holds, where μ denotes the Milnor number.

Assessment of Pulmonary Vascular Impedance in Patients With Severe Pulmonary Arterial Hypertension
Comprehensive Physiology, Volume 16, Issue 4, August 2026.Pulmonary vascular impedance (PVZ) was calculated from clinical PA pressure and RVOT flow velocity profiles. Participants with increased pulmonary vascular resistance have increased PVZ, afterload, and diastolic stiffness. The characteristic impedance (ZC) to mean PA pressure relationship models the effect of proximal vasculature remodeling on ZC for a

Milnor number and chern classes for singular varieties: An introduction
, 2022 We survey how the Milnor number of complex map-germs with an isolated critical point relates to various indices of vector fields on singular varieties, and the way how this number extends via the theory of Chern classes of singular varieties, to the ...

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature
Mathematische Nachrichten, Volume 299, Issue 7, Page 1751-1780, July 2026.ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

The Journal of Finance, Volume 81, Issue 3, Page 1321-1375, June 2026.ABSTRACT We develop a unified theory of blockholder governance and the voting premium in a setting without takeovers or controlling shareholders. A voting premium emerges when a minority blockholder can influence shareholder composition by accumulating votes and buying shares from dissenting shareholders.
