Abstract:
We establish Lyapunov?type inequalities for a class of singular elliptic partial differential equations. As an application of Lyapunov?type inequalities, we obtain lower bounds for the first eigenvalue of the associated singular elliptic partial differential equations. We also make an attempt to answer a question raised by de N�poli and Pinasco in J. Funct. Anal. 270 (2016), no. 6, 1995�2018.
