We study logarithmic gradient estimate to smooth admissible solutions of the Hessian-type equations on Sn. The equations contain a Monge-Ampere equation arising in designing a reflecting surface in geometric optics as... We study logarithmic gradient estimate to smooth admissible solutions of the Hessian-type equations on Sn. The equations contain a Monge-Ampere equation arising in designing a reflecting surface in geometric optics as a special case. 展开更多
