摘要

This research paper aims to explore the features of h-almost conformal \(\vartheta \) ϑ -Ricci-Bourguignon solitons and gradient h-almost conformal \(\vartheta \) ϑ -Ricci-Bourguignon solitons within the context of generalized Robertson Walker spacetimes that include imperfect fluids. The investigation commences with a detailed definition of the unique properties associated with the potential vector field relevant to these solitons. Furthermore, we analyze the characteristics of h-almost conformal \(\vartheta \) ϑ -Ricci-Bourguignon solitons across specific types of imperfect fluid generalized Robertson Walker spacetimes.
