The geometrical theory of diffraction is an extension of geo-metrical optics which accounts for diffraction. It introduces diffracted rays in addition to the usual rays of geometrical optics. These rays are produced by incident rays which hit edges, corners, or vertices of boundary surfaces, or which graze such surfaces.

Research focuses on the fundamental analysis of nonlinear pde, and numerical algorithms for their solution. Current areas of interest include the calculus of variations, nonlinear hyperbolic systems, inverse problems, homogenization, infinite-dimensional dynamical systems, geometric analysis and pde arising in solid and fluid mechanics, materials science, liquid crystals, biology and relativity.
Modern geometry takes many different guises, ranging from geometric topology and symplectic geometry to geometric analysis (which has a significant overlap with pde and geometric measure theory) to dynamical problems. Stanford has long been one of the key centers in all these aspects of geometry. Prominent areas of current research among faculty who work in geometry include ricci and mean curvature flows and other curvature equations, minimal surfaces and geometric measure theory.

The study of geometric properties of sets (typically in euclidean space) through measure theory. It allows to extend tools from differential geometry to a much larger class of surfaces that are not necessarily smooth. A fundamental notion in this subject is that of the rectifiability of a set, which, roughly speaking, entails that the set be locally well approximated by lines or planes.
Keller introduced his geometrical theory of diffraction (gtd) in the 1950s. The geometrical theory of diffraction development was revolutionary, in that it explained the phenomena of wave diffraction entirely in terms of rays for the first time, via a systematic generalization of fermat's principle. In its original form, the geometrical theory of diffraction exhibited singularities at and near.

In mathematics education, the van hiele model is a theory that describes how students learn geometry. The theory originated in 1957 in the doctoral dissertations of dina van hiele-geldof and pierre van hiele (wife and husband) at utrecht university, in the netherlands. The soviets did research on the theory in the 1960s and integrated their findings into their curricula. American researchers did several large studies on the van hiele theory in the late 1970s and early 1980s, concluding that stud.
