The Distinguished Alan J. Goldman Lecture Series- AMS Seminar: Gerard Cornuejols (Carnegie Mellon University) @ Hodson 213

Title: Min-Max Relations for Packing and Covering
Abstract: We consider a family M of subsets of a finite set E. A “cover” is a subset of E that intersects every member of the family M. A “packing” is a set of members of M no two of which intersect. Clearly, the cardinality of a packing is at most that of a cover. We study conditions under which the maximum cardinality of a packing equals the minimum cardinality of a cover. We present recent results obtained jointly with Ahmad Abdi and Dabeen Lee.
