Anais da Academia Brasileira de Ciências, 2002 In this paper we generalize and extend to any Riemannian manifold maximum principles for Euclidean hypersurfaces with vanishing curvature functions obtained by Hounie-Leite.Neste trabalho nós generalizamos e estendemos para uma variedade Riemanniana ...

Refinements on higher order Weil–Oesterlé bounds via a Serre type argument
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract Weil's theorem gives the most standard bound on the maximum number of points Nq(g)$N_q(g)$ of a curve of genus g$g$ over a finite field Fq$\mathbb {F}_q$. This bound was improved by Ihara and Oesterlé for larger genus. A recent point of view allows one to recover these bounds by solving a sequence of semi‐definite programs, and the first two ...

On a Hopf hypersurface of a complex space form [PDF]
, 2010 We prove that if the sectional curvatures for plane sections containing the structure vector field of a real hypersurface in a complex space form are equal to the same constant at every point, then the real hypersurface is a Hopf hypersurface.

h$h$‐Function, Hilbert–Kunz density function and Frobenius–Poincaré function
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract Given ideals I,J$I,J$ of a noetherian local ring (R,m)$(R, \mathfrak {m})$ such that I+J$I+J$ is m$\mathfrak {m}$‐primary and a finitely generated R$R$‐module M$M$, we associate an invariant of (M,R,I,J)$(M,R,I,J)$ called the h$h$‐function.

On the hypersurface of Lüroth quartics
Michigan Mathematical Journal, 2010 The hypersurface of Luroth quartic curves inside the projective space of plane quartics has degree 54. We give a proof of this fact along the lines outlined in a paper by Morley, published in 1919. Another proof has been given by Le Potier and Tikhomirov in 2001, in the setting of moduli spaces of vector bundles on the projective plane.

Planarized and Twisted Intramolecular Charge Transfer: Small Geometric, Huge Photophysical Changes
European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.Molecular motion governs excited state relaxation in aminobenzonitrile donor–acceptor systems. Small structural modifications control single and dual rotations and enable distinct relaxation pathways. Fluorescence spectroscopy, Lippert–Mataga analysis, and theoretical calculations identify multiple excited states, including a dual‐emitting planarized ...

Alexander invariants of hypersurface complements
, 2005 We study Alexander invariants associated to complements of complex hypersurfaces. We show that for a hypersurface V with non-isolated singularities and in general position at infinity, these global invariants of the hypersurface complement are entirely ...
