Доказано, что обобщенное многообразие Кенмоцу, а также специальные обобщенные многообразия Кенмоцу II рода имеют антикоммутативную присоединенную Q-алгебру.А многообразия Кенмоцу и специальные обобщенные многообразия Кенмоцу I рода имеют абелеву присоединенную Q-алгебру. Вводится контактный аналог постоянства типа и подробно исследуются обобщенные многообразия Кенмоцу постоянного типа. Получены условия точечного постоянства типа обобщенных многообразий Кенмоцу на пространстве присоединенной G-структуры. Доказано, что класс GK-многообразий нулевого постоянного типа совпадает с классом многообразий Кенмоцу, а класс GK-многообразий ненулевого постоянного типа конциркулярным преобразованием переводит-ся в почти контактное метрическое многообразие локально эквивалентное произведению шестимерного собственногоNK-многообразия на вещественную прямую.</p></abstract><trans-abstract xml:lang="en"><p>In this work we consider generalized Kenmotsu manifolds, we introduce: the fourth andthe fifth fundamental identities of generalized Kenmotsu manifolds; the first and the secondstructural tensors of generalized Kenmotsu manifolds (and we prove their properties); theconcept of adjoint Q-algebra for generalized Kenmotsu manifolds. We prove that generalizedKenmotsu manifolds and the II kind special generalized Kenmotsu manifolds haveanticommutative adjoint Q-algebra. And the Kenmotsu manifolds and the I kind specialgeneralized Kenmotsu manifolds have Abelian adjoint Q-algebra. The type constancy contactanalog is introduced and the constant-type generalized Kenmotsu manifolds are thoroughlyexamined. We have identified the type point constancy conditions of the generalized Kenmotsumanifolds in the adjoint G-structure space. We prove that the zero constant type GKmanifoldclass coincides with the Kenmotsu manifold class and the non-zero constant typeGK-manifold class can be concircularly transformed into the almost contact metric manifoldslocally equivalent to the product of the six dimensional NK-eigenmanifold and the real straightline.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kirichenko, V.
