报告题目:Vector Optimization with Convex Polynomials

摘要:This talk aims to finnd efficient solutions to a multi-objective programming problem (MP) with convex
polynomial data. To this end, a hybrid method, which allows us to transform (MP) into a family of scalarconvex polynomial optimization problems and does not destroy the properties of convexity, is considered.
Then, we show an existence result of ecient solutions to (MP) under some mild assumption. Apart from
this, we also show that the proposed scalar convex polynomial optimization problem generically possesses
a unique optimal solution. In addition, we establish two kinds of representations of non-negativity of
convex polynomials over convex semi-algebraic sets, and propose two kinds of finite convergence results of
the Lasserre-type hierarchy of semidefinite programming relaxations for the (scalar) convex polynomial
optimization problem under suitable assumptions. Finally, we show that finding efficient solutions to
(MP) can be achieved successfully by solving hierarchies of semidefinite programming relaxations and
checking a at truncation condition.

报告题目: Optimization problem involving the divergence operator
报告地点:维格堂 304 教室
摘要:
We investigate two optimization problems related to a boundary value problem involving the $p$-Laplace type operator. These
optimization problems are formulated relative to the rearrangement of a fixed
function. Under some suitable assumptions, we show that both problems are solvable.
