Polynomial-Factor Deterministic NP-Hardness for SVP in Every lp Norm with p > 2

Isaac M Hair, Amit Sahai

For every constant $2 < p < \infty$ and every constant \[ 0<\varepsilon< \min\left\{\frac{p-2}{4p},\frac18\right\}, \] we show that the $ℓ_{p}$ -shortest vector problem for lattices of…

Deterministic Hardness of Approximation For SVP in all Finite $ℓ_{p}$ Norms

Isaac M Hair, Amit Sahai

We show that, assuming NP $\neq \subseteq$ $\cap_{δ > 0}$ DTIME $(exp n^{δ})$ , the shortest vector problem for lattices of rank $n$ in any finite $ℓ_{p}$ norm is hard to ap…
