Resumen de Betti numbers of the conormal module of licci rings

Mark R. Johnson, Paolo Mantero

• We establish lower bounds for the Betti numbers of the conormal module for licci ideals in a regular local ring. In particular, for a licci Gorenstein ideal I, the i-th Betti number of I/II/I2 is at least 5f2i−1, for i≥1, where fn is the n-th Fibonacci number.
