Let $\Lambda$ be the root lattice corresponding to an ADE root system $R$ of rank $n$. With the ADE assumption, the weight lattice is simply the dual lattice $\Lambda^{\vee}$. Given any weight vector $...

There is a well-known classification result which gives a complete list of all root lattices which can embed into the lattice $E_8$. Moreover, each of these root lattices admits a unique embedding ...

I've recently started to look at elliptic curves and have three basic questions: Is it correct to say that elliptic curves $E$ in the projective plane are in bijective correspondence with lattices $...
