The Kneser Property in \alpha-norm for Nonlinear Differential Equations in Banach Space

In this work, we establish that the set of integral solutions of some partial functional differential equations is connected in the space of continuous functions

ON AFFINE OSSERMAN CONNECTIONS

An affine manifold (M, ∇) is Osserman if the eigenvalues of theaffine Jacobi operators vanishes. In this paper, explicit examples of affine Osser-man connections on 3 and 4-manifolds are constructed and their applications aregiven

Robust observation intervals and stabilization of a wastewater treatment model

In this work, we intend to provide a robust regulation of an aerobic wastewater process model. The model contains two on-line measured states, substrate biomass and dissolved oxygen and, due to exogenous disturbances and functional uncertainties of the kinetics, two unmeasured states, bacteria biomass and recycled bacteria biomass. The first aim consist to find an observation intervals of the unmeasured state variables. The second object aims to build a pair of feedback controls, using the dilution and aeration rates as functions of observed states, to stabilize the substrate biomass and the dissolved oxygen around suitable values

Characterization of some natural transformations between the bundle functors T^{A}\circ T^{\ast} and T^{\ast}\circ T^{A} on Mf

In this paper, we characterize some natural transformations between the bundle functors T^{A}\circ T^{\ast} and T^{\ast}\circ T^{A} on Mf_{m}. In the particular case where A is the space of r-jets at 0 of smooth maps of R --> R, we determine all of these natural transformations. In application, lifts of 1-forms are studied wuth application to the theory of presymplectic structures
