语言同态嵌入到整数中的Frobenius问题

The Frobenius problem for homomorphic embeddings of languages into the integers

Michel Dekking

摘要:

设S是从语言L到满足S(vw)=S(v)+S(w)的整数的映射,其中v,w是来自该语言的所有词.经典的Frobenius问题是问S(L)在自然数中的补数是无限的还是有限的,以及在后一种情况下这个补数中最大元素的值。这也被称为“硬币”问题,L是由有限字母表上的所有单词组成的完整语言。我们解决了Frobenius问题的黄金均值语言,任何Sturmian语言和Thue-Morse语言。我们还考虑了二维嵌入。

英文摘要:

Let S be a map from a language L to the integers satisfying S(vw)=S(v)+S(w) for all words v,w from the language. The classical Frobenius problem asks whether the complement of S(L) in the natural numbers will be infinite or finite, and in the latter case the value of the largest element in this complement. This is also known as the 'coin'-problem, and L is the full language consisting of all words over a finite alphabet. We solve the Frobenius problem for the golden mean language, any Sturmian language and the Thue-Morse language. We also consider two-dimensional embeddings.
