Variational Analysis of Composite Models with Applications to Continuous Optimization

Abstract: The paper is devoted to a comprehensive study of composite models in variational analysis and optimization the importance of which for numerous theoretical, algorithmic, and applied issues of operations research is difficult to overstate. The underlying theme of our study is a systematical replacement of conventional metric regularity and related requirements by much weaker metric subregulatity ones that lead us to significantly stronger and completely new results of first-order and second-order variational an… Show more

“…As promised, now we establish such an estimate for the general case of continuously prox-regular functions. The following proposition and its proof extend those given in [23,Theorem 4.1]. The obtained result shows that subproblem (7.3) always admit an optimal solution under the tilt stability assumption.…”

“…This class strictly includes all the C 2 -cone reducible sets in the sense of [2,Definition 3.135] and encompasses convex polyhedra, the second-order cone, the cone of symmetric and positive semidefinite matrices, etc. Furthermore, parabolic regularity, combined with related developments of [23], occurs to be very instrumental in the study and calculations of second subderivatives and twice epi-differentiability of functions while being employed in our numerical applications given below.…”

“…Twice epi-differentiability has been recognized as an important property in second-order variational analysis with numerous applications to optimization; see the aforemention monograph by Rockafellar and Wets and the recent papers [38,39,40] developing a systematic approach to verify epidifferentiability via parabolic regularity, which is a major second-order property of sets and extendedreal-valued functions.…”

“…One of the important novel features of this approach is the possibility to obtain some quantitative estimates for adjoint functions as discussed in Remark 5.2. We also plan to implement this approach to deriving second-order optimality conditions for variational problems by extending to infinite dimensions and further developing the recent results of second-order variational analysis achieved in [10,11].…”
