Clifford Algebra of Two-forms, Conformal Structures, and Field Equations
نویسنده
چکیده
I review the equivalence between duality operators on two-forms and conformal structures in four dimensions, from a Clifford algebra point of view (due to Urbantke and Harnett). I also review an application, which leads to a set of ”neighbours” of Einstein’s equations. An attempt to formulate reality conditions for the ”neighbours” is discussed.

Monogenic Functions in Conformal Geometry⋆
Monogenic functions are basic to Clifford analysis. On Euclidean space they are defined as smooth functions with values in the corresponding Clifford algebra satisfying a certain system of first order differential equations, usually referred to as the Dirac equation. There are two equally natural extensions of these equations to a Riemannian spin manifold only one of which is conformally invari...
متن کاملThe Design of Linear Algebra and Geometry
Conventional formulations of linear algebra do not do justice to the fundamental concepts of meet, join, and duality in projective geometry. This defect is corrected by introducing Clifford algebra into the foundations of linear algebra. There is a natural extension of linear transformations on a vector space to the associated Clifford algebra with a simple projective interpretation. This opens...
متن کاملApplication of the Schwarz-Christoffel Transformation in Solving Two-Dimensional Turbulent Flows in Complex Geometries
In this paper, two-dimensional turbulent flows in different and complex geometries are simulated by using an accurate grid generation method. In order to analyze the fluid flow, numerical solution of the continuity and Navier-Stokes equations are solved using CFD techniques. Considering the complexity of the physical geometry, conformal mapping is used to generate an orthogonal grid by means of...
متن کاملClifford Algebra of Spacetime and the Conformal Group
We demonstrate the emergence of the conformal group SO(4,2) from the Clifford algebra of spacetime. A Clifford space (that contains spacetime, in particular) does not contain only points (events), but also lines, surfaces, volumes, etc.. All those geometric objects are very elegantly and compactly described by means of the geometric calculus based on Clifford algebra. A subgroup of the Clifford...
متن کاملA Gravity, U(4)× U(4) Yang-Mills and Matter Unification in Clifford Spaces
A brief review of a Conformal Gravity and U(4)×U(4) Yang-Mills Unification model in four dimensions from a Clifford Gauge Field Theory in C-spaces (Clifford spaces) is presented. It based on the (complex) Clifford Cl(4, C) algebra underlying a complexified four dimensional spacetime (8 real dimensions). The 16 fermions of each generation can be arranged into the 16 entries of a 4 × 4 matrix ass...
