Research seminar "Asymptotics, operators and functionals'': Mondays at 16:15-18:15 in Wolfson
Lecture Theatre 4W 1.7.
We aim to discuss the latest results and techniques in the asymptotic analysis of operators, differential equations and functionals, as well as its applications to mechanics, materials and wave propagation.
The talk will usually focus on one or two aspects of a problem of current interest, and is meant to form the basis for an informal discussion during and after the talk. All welcome.
Next talk is on 23 January by myself.
I am EPSRC Fellow and Reader in Mathematics
Here is a link to my 5-year EPSRC-supported project "Mathematical foundations of metamaterials: homogenisation, dissipation and operator theory"
I am always happy to talk to anyone looking for a PhD project. Here are some of the possible research topics.
Please feel free to email me at K.Cherednichenko (at) bath.ac.uk if you are interested.
