Hace 4 días · Abstract In this paper, the inverse spectral problem method is used to integrate a nonlinear sine-Gordon type equation with an additional term in the class of periodic infinite-gap functions. The solvability of the Cauchy problem for an infinite system of Dubrovin differential equations in the class of three times continuously differentiable periodic infinite-gap functions is proved. It is ...
1 de jun. de 2024 · The decades-old Pattern Matching with Edits problem, given a length-n string T (the text), a length-m string P (the pattern), and a positive integer k (the threshold), asks to list all fragments of T that are at edit distance at most k from P.The one-way communication complexity of this problem is the minimum amount of space needed to encode the answer so that it can be retrieved without ...
