Topology of the space of $d$ -pleated surfaces

Sara Maloni, Giuseppe Martone, Filippo Mazzoli +1

Given a maximal geodesic lamination $λ$ on a closed oriented surface $S$ of genus $g$ , the space of $d$ -pleated surfaces with pleating locus $λ$ is an open subset of $\mathrm{Hom}(…

Sharp Schoenberg type inequalities and the de Bruin--Sharma problem

Quanyu Tang, Teng Zhang

In this paper, we confirm two conjectures proposed by Georgiev, Gómez-Serrano, Tao, and Wagner~\cite{GGTW25} on Schoenberg type inequalities of order $4$ , thereby providing a compl…

A new proof of Lee's conjecture on the Frobenius norm via the matrix Cauchy-Schwarz inequality

Teng Zhang

In 2010, Eun-Young Lee conjectured that if $A, B$ are two $n \times n$ complex matrices and $∣ A ∣, ∣ B ∣$ are the absolute values of $A, B$ , respectively, then \[…
