On the origin of the Jacobian conjecture
Lázaro O. Rodríguez Díaz
The Jacobian conjecture is thought to have been proposed by O. H. Keller in 1939. However, we have found that the statement of the conjecture is precisely the main result of a pape…
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…
Étale extensions of polynomial rings are faithfully flat
Lázaro O. Rodríguez Díaz
We apply Ohi's criterion for faithfully flatness of extensions of commutative rings to prove that any étale extension of polynomi…
Gauge theory and G2-geometry on Calabi-Yau links
Omegar Calvo-Andrade, Lázaro O. Rodríguez Díaz, Henrique N. Sá Earp
The -dimensional link of a weighted homogeneous hypersurface on the round -sphere in has a nontrivial null Sasakian structure which is contact Calabi-Yau,…
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…
