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…

Harmonicity of the complex structure on product of trans-Sasakian manifolds
Nidhi Yadav, Punam Gupta, R. K. Gangele
In this paper, we investigate the transverse geometry of trans-Sasakian manifolds and present several significant findings. We analyze the Levi-Civita connection associated with th…

Curvature inequalities for anti-invariant submersion from quaternionic space forms
Kirti Gupta, Punam Gupta, R. K. Gangele
This paper focuses on deriving several curvature inequalities involving the Ricci and scalar curvatures of the horizontal and vertical distributions in anti-invariant Riemannian su…
