Web1 de jan. de 2014 · Haviv and Regev, in , study the lattice isomorphism problem under orthogonal transformations. In the process, they develop a general isolation lemma which they apply to lattice isomorphism and give a \(O^*(k^{O(k)})\) time algorithm for checking if two rank-\(k\) lattices are isomorphic under orthogonal transformations. Webthe lattice isomorphism problem (LIP). More speci cally, we provide: a worst-case to average-case reduction for search-LIP and distinguish-LIP within an isomorphism …

WebWe study the Lattice Isomorphism Problem (LIP), in which given two lattices L_1 and L_2 the goal is to decide whether there exists an orthogonal linear transformation mapping L_1 to L_2. Our main result is an algorithm for this problem running in time n^{O(n)} times a polynomial in the input size, where n is the rank of the input lattices. Web2 de nov. de 2013 · Abstract.
