On the integrality of étale extensions of polynomial rings
Lázaro O. Rodríguez Díaz
Motivated by a valuation theorem, recently obtained by Rangachev, we study the étale extensions of polynomial rings over an algebraically closed field of characteristi…

The superconformal algebra via a Quantum Hamiltonian Reduction of
Lázaro O. Rodríguez Díaz
We prove that the family of non-linear -algebras which are extensions of the superconformal algebra by a primary supercurrent of conformal weight can be re…

The Shatashvili-Vafa superconformal algebra as a Quantum Hamiltonian Reduction of
Reimundo Heluani, Lázaro O. Rodríguez Díaz
We obtain the superconformal algebra associated to a sigma model with target a manifold with holonomy, i.e., the Shatashvili-Vafa algebra as a quantum Hamiltonian r…
