Let M be a positive definite quadratic Z-lattice of rank n+3. If N is a quadratic Z-lattice of rank n which is primitively represented by the genus of M and if all the successive minima of N increase sufficiently quickly, then there exists a global primitive representation of N by M with approximati

Let \(M\) be a positive definite \(Z\)-lattice of rank \(m \geqslant 2 n+3\) and let \(T\) be a finite set of primes containing 2 and those primes \(p\) for which \(M_{p}\) is not unimodular. If \(N\) is a lattice of rank \(n\) which is locally represented by \(M\) and if \(\min (N)\) is sufficientl
