Feb 12	asked	Mathematical significance of the “Dirac conjugate”
Feb 4	comment	Hermitian conjugation and representations of the Lorentzian Clifford algebras $\vec{\gamma}$ is a collection of $2d-1$ matrices ($\gamma ^1$ through $\gamma ^{2d-1}$) of dimension $2^d\times 2^d$.
Feb 4	comment	Hermitian conjugation and representations of the Lorentzian Clifford algebras No. $\gamma ^0$ is supposed to be an $2^d\times 2^d$ matrix with complex entries. (I might have screwed up the dimension, but it is definitely a matrix of the same dimension as $\gamma ^i$ for $i\geq 1$.)
Feb 4	comment	Hermitian conjugation and representations of the Lorentzian Clifford algebras @rschwieb If I understand you correctly, then yes, that is right. I edited the post again to further clarify. Let me know if something is still unclear.
Feb 4	revised	Hermitian conjugation and representations of the Lorentzian Clifford algebras Typo
Feb 4	revised	Hermitian conjugation and representations of the Lorentzian Clifford algebras edited title
Feb 4	comment	Hermitian conjugation and representations of the Lorentzian Clifford algebras @rschwieb I edited the post in an attempt to make my notation more lucid. Please let me know if something is still unclear.
Feb 4	revised	Hermitian conjugation and representations of the Lorentzian Clifford algebras Clarified notation
Feb 4	asked	Hermitian conjugation and representations of the Lorentzian Clifford algebras
Jan 28	asked	Classification of irreducible representations via Casimirs
Nov 22	comment	Isometries of $\mathbb{R}^n$ Sure, but the point was that, in showing that $f$ is linear, I needed to know a priori that $f$ was surjective.
