Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
Each of a set of independent functions that are the solutions to a given differential equation.
- ‘Within the next three years Stone published 10 more papers on various aspects of the theory of orthogonal expansions, especially expansions in terms of eigenfunctions of linear differential equations.’
- ‘From 1939 Titchmarsh concentrated on the theory of series expansions of eigenfunctions of differential equations, work which helped to resolve problems in quantum mechanics.’
- ‘In this thesis he studied the representation of arbitrary functions by the eigenfunctions of partial differential equations and other given sets of functions.’
- ‘In these papers a special role is played by expansions in terms of the eigenfunctions of linear differential operators.’
- ‘In those cases, we see two eigenfunctions with approximately the same statistical wavelength and usually with similar eigenvalues and relative spectral power.’
