TY - EJOU AU - T1 - Applied Optimization and Approximation T2 - International Journal of Mathematical Research PY - 2014 VL - 3 IS - 4 SN - 2306-2223 AB - The present work deals with optimization in kinematics, generalizing previous results of the author. A second theme is maximizing the constrained gain linear function and minimizing the constrained cost function. Elementary notions of optimal control are considered as well. Finally, polynomial approximation results on unbounded subsets in several variables are applied to the moment problem. The existence of the solution of a two dimensional moment problem is characterized in terms of quadratic forms. KW - DO -
