Remarks on some existence theorems for optimal control

First, a remark is made that a growth condition contained in previous papers by Cesari concerning existence theorems for optimal controls can be replaced by a slightly more general condition. In this more general condition, a constant M ɛ ⩾0 is replaced by any function M ɛ ( t )⩾0 which is assumed to be L -integrable in every finite interval.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45215/1/10957_2004_Article_BF00931369.pd
