Source: Differential geometry and its applications. 2021. Vol. 74. P. 101704 (1-12)
Type: статьи в журналах
Date: 2021
Description:
We recall the notion of a differential operator over a map (in linear and non-linear settings) and consider its versions such as formal -differential operators over a map. We study constructions and e

Description:
We consider factorization problem for differential operators on the commutative algebra of densities (defined either algebraically or in terms of an auxiliary extended manifold) introduced in 2004 by

Description:
We consider differential operators on a supermanifold of dimension 1|1. We define non-degenerate operators as those with an invertible top coefficient in the expansion in the ‘superderivative’ D (whic

Description:
Доказана замкнутость сумм некоторых неограниченных операторов, действующих по разным переменным в пространствах квадратично суммируемых функций нескольких переменных. Входящие в такие суммы операторы
