CAPITAL REGION ALGEBRA/NUMBER THEORY SEMINAR 


Speaker:       Professor Hara Charalambous, Univ. at Albany 

Time:          Wednesday, May 5, at 4:30pm    

Place:         Earth Sciences Bldg. ES 143, Univ. at Albany 

Title:         Stable monomial modules 


(Note: This is the last CRANTS talk for this semester, and as 
       is our tradition, we plan to go for dinner afterwards. Please 
       plan to join us. ) 
 

Abstract:

Stable monomial ideals are characterized by  the property that whenever
the monomial  w  is in the ideal and   m  is the largest index of a  
variable that divides  w  then   w x_i/x_m  is also in the ideal. This 
category of ideals includes the lexicographic ideals and the Borel-fixed 
ideals. The resolution of these ideals was given by Eliahou-Kervaire 
in 1987 and the ideals have been widely studied and used ever since.
We will discuss the generalization to monomial modules.
