Twenty-five years of two-dimensional rational conformal field theory [PDF]

, 2009
In this article we try to give a condensed panoramic view of the development of two-dimensional rational conformal field theory in the last twenty-five years.Comment: A review for the 50th anniversary of the Journal of Mathematical Physics.

Hydro & thermo dynamics at causal boundaries, examples in 3d gravity

Journal of High Energy Physics, 2023
We study 3-dimensional gravity on a spacetime bounded by a generic 2-dimensional causal surface. We review the solution phase space specified by 4 generic functions over the causal boundary, construct the symplectic form over the solution space and the 4

Not doomed to fail

Journal of High Energy Physics, 2018
In their recent manuscript “An uplifting discussion of T-duality ” [26], J. Harvey and G. Moore have reevaluated a mod two condition appearing in asymmetric orbifold constructions as an obstruction to the description of certain symmetries of toroidal ...

Implementation and Evaluation of Medical Imaging Techniques Based on Conformal Geometric Algebra

International Journal of Applied Mathematics and Computer Science, 2020
Medical imaging tasks, such as segmentation, 3D modeling, and registration of medical images, involve complex geometric problems, usually solved by standard linear algebra and matrix calculations. In the last few decades, conformal geometric algebra (CGA)

Open-string vertex algebras, tensor categories and operads

, 2003
We introduce notions of open-string vertex algebra, conformal open-string vertex algebra and variants of these notions. These are ``open-string-theoretic,'' ``noncommutative'' generalizations of the notions of vertex algebra and of conformal vertex ...

Notes on the losses compensation of a three-phase power system with DC offset based on geometric algebras

Nonlinear Analysis
In a three-phase symmetric power system, we propose a transformation that converts the original current to a current with minimal losses while preserving the standard constraints. The selected transformation is realized in suitable geometric algebra and

A conformal geometric algebra method for virtual hand modeling and interaction

EURASIP Journal on Image and Video Processing, 2018
Virtual hand usually simulates human hands by mapping the actual shapes of hands to virtual environment and modeling the hand-object manipulations in human machine interactions.

Developing GA-FuL: A Generic Wide-Purpose Library for Computing with Geometric Algebra

Mathematics
The Geometric Algebra Fulcrum Library (GA-FuL) version 1.0 is introduced in this paper as a comprehensive computational library for geometric algebra (GA) and Clifford algebra (CA), in addition to other classical algebras.

DOA Estimation of Cylindrical Conformal Array Based on Geometric Algebra

International Journal of Antennas and Propagation, 2016
Due to the variable curvature of the conformal carrier, the pattern of each element has a different direction. The traditional method of analyzing the conformal array is to use the Euler rotation angle and its matrix representation.

Conical spaces, modular invariance and c p,1 holography

Journal of High Energy Physics, 2021
We propose a non-unitary example of holography for the family of two-dimensional logarithmic conformal field theories with negative central charge c = c p,1 = −6p + 13 − 6p −1.
