Comparison principles and long time behavior for a diffusive Energy Balance Model with vertical resolution

Piermarco Cannarsa, Valerio Lucarini, Patrick Martinez +2

We study a two-layer one-dimensional energy balance model, which allows for vertical energy exchanges between a surface layer and the atmosphere, as well as meridional energy trans…

Analysis of a two-layer energy balance model: long time behaviour and greenhouse effect

Piermarco Cannarsa, Valerio Lucarini, Patrick Martinez +2

We study a two-layer energy balance model, that allows for vertical exchanges between a surface layer and the atmosphere. The evolution equations of the surface temperature and the…

The cost of controlling strongly degenerate parabolic equations

Piermarco Cannarsa, Patrick Martinez, Judith Vancostenoble

We consider the typical one-dimensional strongly degenerate parabolic operator with and , controlled either by a boundary control actin…

Precise estimates for biorthogonal families under asymptotic gap conditions

Piermarco Cannarsa, Patrick Martinez, Judith Vancostenoble

A classical and useful way to study controllability problems is the moment method developed by Fattorini-Russell, based on the construction of suitable biorthogonal families. Sever…

The cost of controlling degenerate parabolic equations by boundary controls

Piermarco Cannarsa, Patrick Martinez, Judith Vancostenoble

We consider the one-dimensional degenerate parabolic equation controlled by a boundary force acting at the degeneracy poin…
