Triviality Results and Conjugate Radius Estimation of Ricci Solitons
Absos Ali Shaikh, Prosenjit Mandal, V. Amarendra Babu
The investigation of Ricci solitons is the focus of this work. We have proved triviality results for compact gradient Ricci soliton under certain restriction. Later, a rigidity res…
