Large Subposets with Small Dimension
Dorais asked for the maximum guaranteed size of a dimension d subposet of an n-element poset. A lower bound of order √ n was found by Goodwillie. We provide a sublinear upper bou...

Perturbed sums-of-squares theorem for polynomial optimization and its applications
We consider a property of positive polynomials on a compact set with a small perturbation. When applied to a Polynomial Optimization Problem (POP), the property implies that the o...

On the coupled continuous knapsack problems: projection onto the volume constrained Gibbs N-simplex
Coupled continuous quadratic knapsack problems (CCK) are introduced in the present study. The solution of a CCK problem is equivalent to the projection of an arbitrary point onto t...
