Planes in quadratic 4-space and associated shapes of lattices
Menny Aka, Konstantin Andritsch, Andreas Wieser
Let be the standard signature quadratic form. To each non-degenerate rational plane in the four-dimensional quadratic space $(\mathbb{Q}^4,…

Seifert surfaces in the four-ball and composition of binary quadratic forms
Menny Aka, Peter Feller, Alison Beth Miller +1
We use composition of binary quadratic forms to systematically create pairs of Seifert surfaces that are non-isotopic in the four-ball. Our main topological result employs Gauss co…

Fibonacci sequences in
Menny Aka
We prove a conjecture due to Gica (Fibonacci Quarterly, 2008). Our proof is simple, uses only elementary abstract algebra, and generalizes to other recursive sequences.
