Mathematician trying to learn string theory

Many string theorists would like to know more algebraic geometry. There are a few of us who know algebraic geometry at a pretty high level (not me) but many more who would like to learn more and feel …

Is the Mendeleev table explained in quantum mechanics?

I am not offended by the suggestion that physicists should follow the standards of mathematical proof, but I think this suggestion and the phrasing of the question demonstrate a lack of understanding …

Example for non equivalent rational full CFTs with same modular invariant (partition function)

I have no idea what a ``symmetric haploid Frobenius algebra" is, so my answer may be terribly naive, but given an even-self dual lattice of rank $d$ there is a well known lattice construction of a rat …

Dimensional regularization in odd dimensions

There a number of papers by Alain Connes on Dimensional Regularization (Dim Reg) in the context of noncommutative field theory. Some of his papers cite P. Breitenlohner and D. Maison, "Dimensional re …

Reference request for Hecke operators for principal congruence subgroup of modular group

I am looking for references that discuss Hecke operators $T_n$ acting on modular forms for the principal congruence subgroup $\Gamma(N)$ of the modular group $SL(2,Z)$ and am happy to restrict to the …

The proof that a vertex algebra can lead to a Wightman QFT

You might find "An Introduction to Conformal Field Theory" by M. Gaberdiel (arXiv:hep-th/9910156v2) useful. He has a brief discussion of how in some cases chiral algebras can be assembled into Conform …

What is the modern understanding of the order of a mock theta function?

Ramanujan introduced mock theta functions and described them by an "order" which he did not define. As a result of the work of Zwegers and others we now have a better understanding of mock theta funct …

Meaning of a phrase from "The algebra of grand unified theories".

I suspect part of the confusion is due to the fact that the $SU(2)$ appearing in the Standard Model gauge group $U(1)\times SU(2) \times SU(3)$ is different from the $SU(2)$ of the Cassen-Condon paper …

Reference request for the determinant of a matrix constructed from Pascal's triangle

One can prove by induction that the matrix $M^{(n)}$ given by $$ \begin{pmatrix} 1 & 1 & 1 & 1 & \dots & \binom{n}{0} \\ 1 & 2 & 3 & 4 & \dots & \binom{n+1}{1} \\ 1 & 3 & 6 & 10 & \dots & \binom{n+2}{ …
