On allocating seats to parties and districts: apportionments [PDF]

The paper presents the problem of choosing the representatives in an assembly when the whole electoral region is subdivided into electoral districts. Because of the two dimensions, geographical (districts) and political (parties), the problem is called ...

Periodic solutions for nonautonomous second order Hamiltonian systems with sublinear nonlinearity

Boundary Value Problems, 2011
Some existence and multiplicity of periodic solutions are obtained for nonautonomous second order Hamiltonian systems with sublinear nonlinearity by using the least action principle and minimax methods in critical point theory.

Existence of periodic solutions for non-autonomous second-order Hamiltonian systems

Electronic Journal of Differential Equations, 2013
The purpose of this paper is to study the existence of periodic solutions for a class of non-autonomous second order Hamiltonian systems. New results are obtained by using the least action principle and the minimax methods, without the so-called Ahmad-

Minimax Adaptive Control and Estimation [PDF]

This thesis presents five papers on minimax adaptive control and estimation. Minimax adaptive estimation is a framework for output prediction and state estimation that provides a priori computable performance bounds for esti- mators.

Fixed Points,Coincidence Points and Maximal Element Theorems With Applications to Generlized Equilibrium Problems and Minimax Theory

, 2011
[[abstract]]In this paper, using a generalization of the Fan–Browder fixed point theorem, we obtain a new fixed point theorem for multivalued maps in generalized convex spaces from which we derive several coincidence theorems and existence theorems for ...

Nonsubjective priors via predictive relative entropy regret

, 2006
We explore the construction of nonsubjective prior distributions in Bayesian statistics via a posterior predictive relative entropy regret criterion. We carry out a minimax analysis based on a derived asymptotic predictive loss function and show that ...
