  • Simply definable well-orderings of the reals, Dissertation, UC Berkeley, 2003. Signature page. (Advisors: John Steel, Hugh Woodin). MR2705176. Errata: The complexity of the well-ordering mentioned in p. 36 should be \Sigma^1_6, see here (the optimal complexity of \Sigma^1_3 is achieved by more elaborate arguments, see here). Wisest to ignore Chapter 4.
  • El problema de los cardinales singulares, Apuntes Matemáticos 37, Departamento de Matemáticas, Universidad de los Andes, Bogotá, 1996. (This is a reprint of my undergraduate dissertation, written under the supervision of Xavier Caicedo.)
