Strong NP-Completeness of Unrestricted Balanced Mobiles

Andrei Popa, Alexandru Popa

A mobile is a rooted full binary tree whose leaves carry positive integer weights. The imbalance of an internal node is the absolute difference between the total weights of its two…

A decomposition of Weyl group multiple Dirichlet series for symmetrizable Kac-Moody root systems

Alexandru A. Popa, Jack Walsh

We study twisted Weyl group multiple Dirichlet series attached to symmetrizable Kac-Moody root systems, using the Chinta-Gunnells method to construct their $p$ -parts. Our main resu…

Complexity and Algorithms for Unary Translocation Distance

Maria Constantin, Adrian Miclăuş, Alexandru Popa +1

Given a finite set of integers $A$ , a \emph{unary translocation} produces a new set $A^{'} = A \cup {u, v}$ , where $u$ and $v$ are nonnegative integers satisfying $x + y = u + v$ for some…
