Asymptotics, Operators, and Functionals


Leading the discussion in 2019:

16 January Conference "Operators, Operator Families and Asymptotics II"

21 January Rafael del Río (IIMAS-UNAM) (Topic: Resonances under rank-one perturbations) Abstract: I shall discuss resonances generated by rank-one perturbations of self-adjoint operators with eigenvalues embedded in the continuous spectrum. I shall demonstrate the instability of these eigenvalues and an "almost-exponential" decay for the associated resonant states. I shall then show how these results can be applied to Sturm-Liouville operators.

28 January Josué Cangas (IIMAS-UNAM) (Topic: Dissipative linear relations on orthogonal polynomials)

4 February Kirill Cherednichenko (Topic: Electromagnetic time-dispersive media ("metamaterials") by homogenisation I)

11 February Kirill Cherednichenko (Topic: Electromagnetic time-dispersive media ("metamaterials") by homogenisation II)

18 February Elaine Crooks (Swansea) (Topic: Compensated convexity and its applications)
