Rational Points in the Noether-Lefschetz Locus of Moduli Spaces of K3 Surfaces
We give a characterization of rational points lying on the Noether-Lefschetz locus of moduli spaces of K3 surfaces by studying their lifting properties under some natural coverings of the ambient space. We then prove that the Bombieri-Lang conjecture impli ...
Oxford Univ Press2024Latest findings on the behaviour factor q for the seismic design of URM buildings
Recent earthquakes as the 2012 Emilia earthquake sequence showed that recently built unreinforced masonry (URM) buildings behaved much better than expected and sustained, despite the maximum PGA values ranged between 0.20-0.30 g, either minor damage or str ...
SPRINGER2022Strictly Real Fundamental Theorem Of Algebra Using Polynomial Interlacing
Without resorting to complex numbers or any advanced topological arguments, we show that any real polynomial of degree greater than two always has a real quadratic polynomial factor, which is equivalent to the fundamental theorem of algebra. The proof uses ...
CAMBRIDGE UNIV PRESS2021Two-dimensional nanochannel membranes for molecular and ionic separations
Shaoyu Wang, Guangwei He, Yifan Li, Zheyu Jiang
Two-dimensional (2D) nanosheets have emerged as promising functional materials owing to their atomic thickness and unique physical/chemical properties. By using 2D nanosheets as building blocks, diverse kinds of two-dimensional nanochannel membranes (2DNCM ...
ROYAL SOC CHEMISTRY2020Rationally almost periodic sequences, polynomial multiple recurrence and symbolic dynamics
A set is called rational if it is well approximable by finite unions of arithmetic progressions, meaning that for every there exists a set , where $a_{1},\ldots ,a_ ...
2019Presymplectic convexity and (ir)rational polytopes
In this paper, we extend the Atiyah-Guillemin-Sternberg convexity theorem and Delzant's classification of symplectic toric manifolds to presymplectic manifolds. We also define and study the Morita equivalence of presymplectic toric manifolds and of their c ...
2019Moving on: Is Existenzminimum Still Relevant?
In the inter-war period, progressive architects confronted the building of mass housing with an analogy with rational and functional workplaces. At the 2nd CIAM (Congres Internationaux d'Architecture Moderne), held in Frankfurt in 1929, this was tested aga ...
2019Rationally isomorphic hermitian forms and torsors of some non-reductive groups
Let R be a semilocal Dedekind domain. Under certain assumptions, we show that two (not necessarily unimodular) hermitian forms over an R-algebra with involution, which are rationally isomorphic and have isomorphic semisimple coradicals, are in fact isomorp ...
