Operators, Operator Families and Asymptotics II
Join us in January 2019 for the second conference in this series, supported by London Mathematical Society, Newton Fund, EPSRC and Bath IMI.
The conference, which is the second in a series that we hope to run every 3 years, aims at making an overview of the state of the art in a rapidly developing area of analysis concerned with application of the techniques of operator theory to the asymptotic study of parameter-dependent differential equations and boundary-value problems.
From the physical point of view, the parameter normally represents a length-scale in the situation modelled by the equation: for example, a wavelength in wave propagation, or the inhomogeneity size in the theory of periodic composites. The theory of linear operators in a Hilbert space (symmetric, self-adjoint, dissipative, non-selfadjoint), which prior to the first conference in the series had enjoyed several decades of outstanding progress, had been, for much of its time, restricted to abstract analysis of general classes of operators, accompanied by ad-hoc examples and applications to perturbations of the Laplace operator. The first meeting in 2016 contributed to recent developments concerning the above link, in particular clarifying the role of operator-based techniques in the development of mathematical foundations for metamaterials.
The second meeting will outline the next steps in this process, generating new research directions in the asymptotic study of operator families, where the abstract and applied streams are aligned with each other. The above subject area is currently in the state of maturing for the next breakthrough in the applications of mathematics to the real-world technologies that depend on understanding the behaviour of solutions to parameter-dependent boundary-value problems of mathematical physics. One notable example of this interaction is found in the development of techniques for manufacturing composite materials that exhibit negative refraction ("metamaterials"): analysis of operators and their families offers a cost-effective way to explore possible ways to obtain such composites, and vice versa, the practical needs give a massive stimulus to further development of this classical area of analysis.
