lattice orthogonal complement
Let $A\in \mathbb{Z}^{m\times n}$ ($m<n$) be a matrix with orthogonal rows. Further assume that the gcd of the coefficients in each row of $A$ is $1$.
Consider $\ker A\cap \mathbb{Z}^n = \{x\in\math …

shortest lattice point solution to a linear system
Consider the lattice $\mathbb{Z}^n$ and a real matrix $A\in \mathbb{R}^{m\times n}$ ($m<n$) with orthonormal rows. Let $y\in A\mathbb{Z}^n\setminus\{0\}$ and consider the equation $Ax=y$. Is there a ( …
