The aim of this journal is to promote the application of mathematics to problems from engineering and the applied sciences. It also aims to emphasize the intrinsic unity, through mathematics, of the fundamental problems of applied and engineering science. The scope of the journal includes the following:

? Mathematics: Ordinary and partial differential equations, Integral equations, Asymptotics, Variational and functional?analytic methods, Numerical analysis, Computational methods.

? Applied Fields: Continuum mechanics, Stability theory, Wave propagation, Diffusion, Heat and mass transfer, Free?boundary problems; Fluid mechanics: Aero? and hydrodynamics, Boundary layers, Shock waves, Fluid machinery, Fluid?structure interactions, Convection, Combustion, Acoustics, Multi?phase flows, Transition and turbulence, Creeping flow, Rheology, Porous?media flows, Ocean engineering, Atmospheric engineering, Non-Newtonian flows, Ship hydrodynamics; Solid mechanics: Elasticity, Classical mechanics, Nonlinear mechanics, Vibrations, Plates and shells, Fracture mechanics; Biomedical engineering, Geophysical engineering, Reaction?diffusion problems; and related areas.

The Journal also publishes occasional invited 'Perspectives' articles by distinguished researchers reviewing and bringing their authoritative overview to recent developments in topics of current interest in their area of expertise. Authors wishing to suggest topics for such articles should contact the Editors-in-Chief directly.

Prospective authors are encouraged to consult recent issues of the journal in order to judge whether or not their manuscript is consistent with the style and content of published papers.
