New Transference Theorems on Lattices Possessing n^\epsilon-unique Shortest Vectors
Wei Wei, Chengliang Tian, and Xiaoyun Wang
Abstract
We prove three optimal transference theorems on lattices possessing $n^{\epsilon}$-unique shortest vectors which relate to the successive minima, the covering radius and the minimal length of generating vectors respectively. The theorems result in reductions between GapSVP$_{\gamma'}$ and GapSIVP$_\gamma$ for this class of lattices. Furthermore, we prove a new transference theorem giving an optimal lower bound relating the successive minima of a lattice with its dual. As an application, we compare the respective advantages of current upper bounds on the smoothing parameter of discrete Gaussian measures over lattices and show a more appropriate bound for lattices whose duals possess $\sqrt{n}$-unique shortest vectors.
