DDVV conjecture for Riemannian maps from quaternionic space forms
Kirti Gupta, Punam Gupta, R. K. Gangele
In this paper, we investigate the DDVV-type inequality for Riemannian maps from quaternionic space forms to Riemannian manifolds. We also discuss the equality case of the derived i…

On H-Conformal Semi-invariant Submersion
Punam Gupta, Kirti Gupta
We explore h-conformal semi-invariant submersions and almost h-conformal semi-invariant submersions originating from quaternionic Kähler manifolds to Riemannian manifolds. Our inve…
