DESCRIPTION:Title: The Wiles-Lenstra-Diamond numerical criterion in higher 
 codimensions.\n\nAbstract: I will report on recent joint work with Srikant
 h Iyengar and Jeff Manning. We give a development of numerical criterion t
 hat was used by Wiles as an essential ingredient in his approach to modula
 rity of elliptic curves over $Q$. The patching method introduced by Wiles 
 and Taylor has been developed considerably while the numerical criterion h
 as lagged behind. We prove new commutative algebra results that lead to a 
 generalisation of the Wiles-Lenstra-Diamond numerical criterion in situati
 ons of positive defect (as arise when proving modularity of elliptic curve
 s over number fields with a complex place). A key step in our work is the 
 definition of congruence modules in higher codimensions which should be re
 levant to studying eigenvarieties at classical points.\n\n \n\nON-SITE :
