In this poster we address approximate controllability problems via multiplicative controls, motivated by our interest in some differential models for the study of climatology.
One of the first attempts to model the interaction between large ice masses and solar radiation on climate is the Budyko-Sellers model. This model studies how extensive is the climate response to an event such as a sharp increase in greenhouse gases. The Budyko-Sellers model is interested in the role played by continental and oceanic areas of ice on climate change.
The 1-d Budyko-Sellers model reduces to nonlinear degenerate parabolic equation with Neumann boundary condition.
For this problem we will discuss recent results guaranteeing global approximate controllability in large time by bilinear control. |
