摘要:

我们研究了在具有精细群分次的上三角矩阵代数上带有齐次对合的分次多项式恒等式。我们计算了它们的多项式恒等式以及相对自由代数的一组基,考虑了任意基域。当基域的特征为零时,我们得到了余维数序列的渐近行为。作为推论,我们计算了赋予任意群分次和任意齐次对合的同一代数的指数和第二指数。

英文摘要:

We study the graded polynomial identities with a homogeneous involution on the algebra of upper triangular matrices endowed with a fine group grading. We compute their polynomial identities and a basis of the relatively free algebra, considering an arbitrary base field. We obtain the asymptotic behaviour of the codimension sequence when the characteristic of the base field is zero. As a consequence, we compute the exponent and the second exponent of the same algebra endowed with any group grading and any homogeneous involution.
