关于运算的结合谱

On associative spectra of operations

Sebastian Liebscher, Tamás Waldhauser

摘要:

一个操作与关联的距离可以通过它的关联谱来“测量”,关联谱是一个适当的正整数序列。缔合光谱是由B. Csákány和T. Waldhauser在2000年为二元运算编写了一个程序(参见arXiv:1102.2124)。我们将这一概念推广到p元运算,解释关联谱方程理论,并使用这种解释找到一个表征精细谱,构造多项式关联谱,并表明有连续许多不同的谱。此外,括号的等价表示进行了研究。

英文摘要:

The distance of an operation from being associative can be "measured" by its associative spectrum, an appropriate sequence of positive integers. Associative spectra were introduced in a publication by B. Csákány and T. Waldhauser in 2000 for binary operations (see arXiv:1102.2124). We generalize this concept to p-ary operations, interpret associative spectra in terms of equational theories, and use this interpretation to find a characterization of fine spectra, to construct polynomial associative spectra, and to show that there are continuously many different spectra. Furthermore, an equivalent representation of bracketings is studied.
