摘要:
AbstractIn this paper we study parametric optimal control problems monitored by nonlinear evolution equations. The parameter appears in all the data, including the nonlinear operator. First we show that for every value of the parameter, the optimal control problem has a solution. Then we study how these solutions as well as the value of the problem respond to changes in the parameter. Finally, we work out in detail two examples of nonlinear parabolic optimal control systems.

摘要:
AbstractPointwise estimates are obtained for the simultaneous approximation of a function f ϵCq[‐1,1] and its derivatives f(1), …, f(q)by means of an arbitrary sequence of bounded linear projection operatorsLnwhich mapC[‐1,1] into the polynomials of degree at mostn, augmented by the interpolation of f at some points ne

AbstractResults on the degree of approximation of continuous or Lipschitz‐continuous functions f:Sn−1→ ℝ on the sphere in ℝnby spherical functions of degreekare given in terms ofkandn, strengthening results of Newman and Shapiro. An example of (restriction of) a norm shows the result to be the best possible inkandn. Further, results for smoother functions are
