Let S be a certain affine algebraic surface over Q such that it
admits a regular map to A2/Q. We show that any non-trivial
torsion line bundle in the relative Picard group

History and Overview
A polyhedral product is a natural subspace of a Cartesian product that is
specified by a simplicial complex. The modern formalism arose as a
generalization of the spaces known as moment-angle complexes which were
developed within the nascen...

Given a half-integral weight holomorphic Kohnen newform f on Γ0(4),
we prove an asymptotic formula for large primes p with power saving error

We consider an atomic congestion game in which each player i participates
in the game with an exogenous and known probability pi∈(0,1],
independently of everybody else, or stays out and incurs no cost. We compute
the parameterized ...

Persistent Betti numbers are a major tool in persistent homology, a subfield
of topological data analysis. Many tools in persistent homology rely on the
properties of persistent Betti numbers considered as a two-dimensional

A face cover perspective to ℓ1 embeddings of planar graphs

It was conjectured by Gupta et al. [Combinatorica04] that every planar graph
can be embedded into ℓ1 with constant distortion. However, given an
n-vertex weighted planar graph, the best upper bound on the distortion is
only $O(\sqrt...

We propose a new variational approach to finding multiple critical points for
strongly indefinite problems without assuming the weak upper semicontinuity on
the variational functionals. By this approach, we obtain the existence of

In the recent years constructing time-invariant spatial-focusing beampatterns
by using frequency diverse arrays (FDAs) is conveyed in several papers. Further

Textual information in a captured scene plays an important role in scene
interpretation and decision making. Though there exist methods that can
successfully detect and interpret complex text regions present in a scene, to
