# Reprint: On lattice points in $n$-dimensional star bodies (1946)

### Kurt Mahler

## Abstract

Let $F(X)=F(x_{1},…,x_{n})$ be a continuous non-negative function of $X=(x_{1},…,x_{n})$ that satisfies $F(tX)=∣t∣F(X)$ for all real numbers $t$. The set $K$ in $n$-dimensional Euclidean space $R_{n}$ defined by $F(X)⩽1$ is called a star body. In this paper, Mahler studies the lattices $Λ$ in $R_{n}$ which are of minimum determinant and have no point except $(0,…,0)$ inside $K$. He investigates how many points of such lattices lie on, or near to, the boundary of $K$, and considers in detail the case when $K$ admits an infinite group of linear transformations into itself.
