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.

Web1 de mar. de 2024 · In this section, we explore two possible methods to solve the finite field isomorphism problem. Such an isomorphism will be described as an n-by-n matrix M. The first approach is based on lattice reduction. The second approach is a highly non-linear attack of unknown but, we believe, high difficulty. 2.4.1 Lattice Attack of (\(\dim \approx … Web24 de mar. de 2024 · A lattice isomorphism is a one-to-one and onto lattice homomorphism .

WebAbstract We 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. Web11 de mai. de 2016 · LDP asks how "similar" two lattices are. I.e., what is the minimal distortion of a linear bijection between the two lattices? LDP generalizes the Lattice Isomorphism Problem (the lattice analogue of Graph Isomorphism), which simply asks whether the minimal distortion is one.
Web6 de fev. de 2009 · We prove that the related problem of counting vertices of the Voronoi cell is #P-hard. As a byproduct of our construction, we show that the lattice isomorphism problem is at least as difficult as the graph isomorphism problem. We turn to practical algorithms for the covering radius problem in Section 3.
