Efficient lifts into odd dimensions of Spherical $5$ - and $7$ -designs with Balanced Halves

Konstantin Delchev, Boryan Yordanov

We propose constructions of spherical $5$ - and $7$ -designs in odd dimensions by lifting balanced halves of even-dimensional designs to several layers of suitable latitudes. For eve…

The 2-Adic Valuation of the Order of the All-Ones Class in the Sandpile Group of a Square

Turgay Akyar, Artem Beliakov, Konstantin Delchev +6

Place one grain at every nonsink vertex of the wired $n \times n$ square, and let $L (n)$ be the order of this operation in the sandpile group. Thus $L (n)$ is the least positive $q$ …
