利用变分分析方法,研究了Banach空间中的次光滑多值函数。利用正规锥和上导数,给出了这类集值函数镇定的一些刻画。对Asplund空间得到了更清晰的结果。我们还提出了一些精确的公式的平静度的模量。作为应用,我们给出了非凸不等式的一些误差界结果,改进和推广了已有的误差界结果。
Using variational analysis techniques, we study subsmooth multifunctions in Banach spaces. In terms of the normal cones and coderivatives, we provide some characterizations for such multifunctions to be calm. Sharper results are obtained for Asplund spaces. We also present some exact formulas of the modulus of the calmness. As applications, we provide some error bound results on nonconvex inequalities, which improve and generalize the existing error bound results.
