SUMMARY:Homogenisation as control -- Mimicking eigenvalue problems - Jean 
 Lagacé (King's College London)

DESCRIPTION:Homogenisation is a powerful tool from applied mathematics whi
 ch can be used to probe the boundary of the space of parameters for which 
 a problem is defined. In this talk\, I will discuss some of the ways in wh
 ich this tool has been applied to spectral geometry in the last 5 years\, 
 in particular how the behaviour of one eigenvalue problem can mimick that 
 of a different one. Examples include optimal bounds for Steklov eigenvalue
 s\, flexibility of the Schr&ouml\;dinger and Steklov eigenvalue optimisati
 on problem\, approximation of minimal surfaces\, etc.
