WebWe consider the problem of calculation of the critical amplitudes at infinity by means of the self-similar continued root approximants. Region of applicability of the continued root approximants is extended from the determinate (convergent) problem with well-defined conditions studied before by Gluzman and Yukalov (Phys. Lett.

Web2 days ago · Previously, it was found that there are 34 lattices which must be considered and the question was partially answered for one of them. Here we use results in the sphere packing problem to completely answer this question for 21 cases, and show that a negative answer to this question would constitute a new optimal lattice sphere packing in ... WebIt is clearly a lattice because, if λ occurs in V and μ occurs in U, then λ + μ occurs in V ⊗ U. As you say, it is enough to show that L = X ∗ ( T). Also, note that the root lattice is in L. Let λ be any element of X ∗ ( T). Let s: T → C be the function t ↦ ∑ w ∈ W λ ( w ( t)). Web9 Feb 2024 · Weights which lie in the weight lattice are called .
