On the lattice isomorphism problem
WebKeywords: Lattice Isomorphism Problem, Lattice Reduction, Proablev Algorithm 1 Introduction wTo lattices Λ,Λ′⊂Rn are said to be isomorphic if there exists a rotation between them, that is a linear orthogonal map O∈O n(R) such that O·Λ = Λ′.

As above, we say that f is a kernel operator on X to mean a kernel operator on (P(X),⊆). For a weakly …

Our main result is an algorithm for this problem running in time nO(n) times a polynomial in the input size, where n is the rank of the input lattices.
