项目摘要

We continue to use various techniques to study gradings on algebras: associative, Lie, Jordan and respective superalgebras. Most of these techniques are connected to Hopf algebras, hyperalgebras and group schemes, and work effectively in the case of finite-dimensional algebras over fields of arbitrary characteristic. We will continue using functional identities, which are an effective tool in the case, where the algebras of sufficiently large dimension, and the coefficients need not be in a field. We will pay more attention to various classes of nonassociative algebras which will help us in the study of gradings on exceptional Lie algebras. We plan to continue studying graded identities on associative and Lie algebras since they turn out to be an effective sustitute of ordinary polynomial identities which are very hard to determine even in the simplest cases of matrix algebras. We will continue our research of the growth of various algebraic objects, like groups, associative and Lie algebras, their actions and modules, with the goal of constructing the objects close to free by their growth and still satisfying interesting finiteness conditions. This is important for the constructions arising in the study of Burnside-type problems. We will continue working in the area of infinite-dimensional Lie algebras and superalgebras, in particular, locally finite algebras, having in mind infinite-dimensional simple Lie algebras, their structure and representations.

我们继续使用各种技术来研究代数的分级：结合，李，约旦和各自的超代数。大多数这些技术都连接到Hopf代数，超代数和群计划，并有效地工作在有限维代数的情况下，在字段的任意特征。我们将继续使用函数恒等式，这是一个有效的工具，在这种情况下，代数足够大的维度，和系数不需要在一个领域。我们将更多地关注各类非结合代数，这将有助于我们研究特殊李代数的分级。我们计划继续研究分级的身份结合和李代数，因为他们原来是一个有效的替代普通多项式身份是很难确定，即使在最简单的情况下，矩阵代数。我们将继续研究各种代数对象的增长，如群，结合代数和李代数，它们的作用和模，目标是通过它们的增长来构建接近自由的对象，并且仍然满足有趣的有限性条件。这对于Burnside型问题研究中出现的构造是很重要的。我们将继续工作在该地区的无限维李代数和超代数，特别是局部有限代数，在头脑中无限维简单李代数，他们的结构和表示。
