On integers that are representable as the sum of two units
Robin Visser, Volker Ziegler
Let be a number field of degree with maximal order . We show that under certain conditions on , which in particular are always satisfied if is odd or…
Repellent properties of perfect powers on partition functions: a heuristic approach
Summer Haag, Praneel Samanta, Swati +3
In 2013, Sun conjectured that the partition function is never a perfect power for . Building on this, Merca, Ono, and Tsai recently observed that for any fixed int…
Asymptotics of -universal lattices over number fields
Dayoon Park, Robin Visser, Pavlo Yatsyna +1
We prove an explicit asymptotic formula for the logarithm of the minimal ranks of -universal lattices over the ring of integers of totally real number fields. We also show that,…
Sums of two units in number fields
Magdaléna Tinková, Robin Visser, Pavlo Yatsyna
Let be a number field with ring of integers . Let be the set of positive integers such that there exist units $\varepsilon, δ\in \mathcal{O}_…
