The geometric algebra as defined by D. Hestenes is compared with a constructive definition of Clifford algebras. Both approaches are discussed and the equivalence between a finite geometric algebra and the universal Clifford algebra Rp, q is shown. Also an intermediate way to construct Clifford algebras is sketched. This attempt to conciliate two separated approaches may be useful taking into account the recognized importance of Clifford algebras in theoretical and applied physics.

TLDR
This tutorial provides a basic introduction to geometric algebra and presents formulations of known electrical engineering and signal processing concepts to illustrate some inherent advantages of geometric algebra for formulating and solving problems involving vectors.

Constructing a “string theory” through the use of geometric algebra

String theory has allowed us to make advances in theoretical physics by exchanging point particles for one-dimensionally extended ‘strings’ as elementary object; for example string theories are the

Fourvector algebra

The algebra of fourvectors is described. The fourvectors are more appropriate than the Hamilton quaternions for its use in Physics and the sciences in general. The fourvectors embrace the 3D vectors

A Proposal of an Algebra for Vectors and an Application to Electromagnetism

A new mathematical structure intended to formalize the classical 3D and 4D vectors is briefly described. This structure is offered to the investigators as a tool that bears the potential of being

A pr 2 02 1 Gravity as a ‘ Third ’ Quantization Gauge Theory with Minkowski Metric , Non-Zero Torsion and Curvature

It is understood that, in general, a global and unique vacuum state cannot be considered in a curved space. Hence, we have introduced a geometry that, in addition of having non-zero local curvature

A Different Polar Representation for Generalized and Generalized Dual Quaternions

In this paper, we present a new polar representation for generalized quaternions and generalized dual quaternions. In this different polar form representation, as in the Cayley–Dickson form, a

A `Third' Quantization Constructed for Gauge Theory of Gravity

In general, a global and unique vacuum state cannot be constructed for a curved space. As a remedy, we introduce a curved space background geometry with a Minkowski metric tensor and locally nonzero

Visual Servoing on the Sphere Using Conformal Geometric Algebra

This paper deals with a visual servoing scheme, which uses a paracatadioptric sensor as visual input. The paracatadioptric sensor provides a wide field of view while maintaining the single center of

Pattern Classification Approaches for Breast Cancer Identification via MRI: State-Of-The-Art and Vision for the Future

TLDR
The proposed data fusion approaches provide a novel Artificial Intelligence (AI) based framework for more robust image registration that can potentially advance the early identification of heterogeneous tumour types, even when the associated imaged organs are registered as separate entities embedded in more complex geometric spaces.

Dirac equation and Clifford algebra

The Dirac equation is rewritten in the framework of a Clifford algebra, revealing some new features, of which the most interesting is the U(1)×SU(2) symmetry of the corresponding Lagrangian.

The applications of Clifford algebras to crystallography using Mathematica

The discovery of materials such as incommensurate structures and quasicrystals makes necessary to extend crystallography to more than three dimensions. In this work, we explore the use of Clifford
