Hans Grauert (8 February 1930 in Haren, Emsland, Germany – 4 September 2011) was a German mathematician.
 He is known for major works on several complex variables, complex manifolds and the application of sheaf theory in this area, which influenced later work in algebraic geometry.
 Together with Reinhold Remmert he established and developed the theory of complex-analytic spaces.
 He became Professor at the University of Göttingen in 1958, as successor to C. L. Siegel.
 The lineage of this chair traces back through an eminent line of mathematicians: Weyl, Hilbert, Riemann, and ultimately to Gauss.
 Until his death, he was professor emeritus at Göttingen.
In differential geometry, the Weyl curvature tensor, named after Hermann Weyl, is a measure of the curvature of spacetime or, more generally, a pseudo-Riemannian manifold.
 Like the Riemann curvature tensor, the Weyl tensor expresses the tidal force that a body feels when moving along a geodesic.
 The Weyl tensor differs from the Riemann curvature tensor in that it does not convey information on how the volume of the body changes, but rather only how the shape of the body is distorted by the tidal force.
 The Ricci curvature, or trace component of the Riemann tensor contains precisely the information about how volumes change in the presence of tidal forces, so the Weyl tensor is the traceless component of the Riemann tensor.
 It is a tensor that has the same symmetries as the Riemann tensor with the extra condition that it be trace-free: metric contraction on any pair of indices yields zero.
In mathematics, Weyl's theorem or Weyl's lemma might refer to one of a number of results of Hermann Weyl.
 These include
In algebra, a Weyl module is a representation of a reductive algebraic group, introduced by and named after Hermann Weyl.
 In characteristic 0 these representations are irreducible, but in positive characteristic they can be reducible, and their decomposition into irreducible components can be hard to determine.
Hermann Klaus Hugo Weyl, {'1': ", '2': ", '3': 'ForMemRS', '4': "} (] ; 9 November 1885 – 8 December 1955) was a German mathematician, theoretical physicist and philosopher.
 Although much of his working life was spent in Zürich, Switzerland and then Princeton, he is associated with the University of Göttingen tradition of mathematics, represented by David Hilbert and Hermann Minkowski.
Weyl fermions are massless chiral fermions that play an important role in quantum field theory and the standard model.
 They are considered a building block for fermions in quantum field theory, and were predicted from a solution to the Dirac equation derived by Hermann Weyl called the Weyl equation.
 For example, one-half of a charged Dirac fermion of a definite chirality is a Weyl fermion.
 They have not been observed as a fundamental particle in nature.
 Weyl fermions may be realized as emergent quasiparticles in a low-energy condensed matter system.
 This was first predicted by C. Herring in the context of electronic band structures of solid state systems such as electronic crystals.
 The first (non-electronic) liquid state which is suggested has similarly emergent but neutral excitation and theoretically interpreted superfluid's chiral anomaly as observation of Fermi points is in Helium-3 A liquids.
 Crystalline TaAs is the first discovered topological Weyl fermion semimetal exhibiting topological surface Fermi arcs where Weyl fermion is electrically charged along the line of original suggestion by C. Herring.
 An electronic Weyl fermion is not only charged but stable at room temperature where there is no such superfluid or liquid state known.
The Weyl–Schouten theorem in mathematics (named after Hermann Weyl and Jan Arnoldus Schouten) says that a Riemannian manifold of dimension "n" with "n" ≥ 3 is conformally flat if and only if the Schouten tensor is a Codazzi tensor for "n" = 3, or the Weyl tensor vanishes for "n" > 3.
In physics, particularly quantum field theory, the Weyl equation is a relativistic wave equation for describing massless spin-1/2 particles called Weyl fermions.
 It is named after the German physicist Hermann Weyl.
In combinatorial geometry, the Weyl distance function is a function that behaves in some ways like the distance function of a metric space, but instead of taking values in the positive real numbers, it takes values in a group of reflections, called the Weyl group (named for Hermann Weyl).
 This distance function is defined on the collection of chambers in a mathematical structure known as a building, and its value on a pair of chambers a minimal sequence of reflections (in the Weyl group) to go from one chamber to the other.
 An adjacent sequence of chambers in a building is known as a gallery, so the Weyl distance function is a way of encoding the information of a minimal gallery between two chambers.
 In particular, the number of reflections to go from one chamber to another coincides with the length of the minimal gallery between the two chambers, and so gives a natural metric (the gallery metric) on the building.
 According to , the Weyl distance function is something like a geometric vector: it encodes both the magnitude (distance) between two chambers of a building, as well as the direction between them.
In mathematics, Weyl's lemma, named after Hermann Weyl, states that every weak solution of Laplace's equation is a smooth solution.
 This contrasts with the wave equation, for example, which has weak solutions that are not smooth solutions.
 Weyl's lemma is a special case of elliptic or hypoelliptic regularity.
