In graph theory, the term critical is usually used to describe a graph which has some property which is lost upon some alteration to the graph (such as vertex deletion, edge deletion or addition).  Criticality is often used in the proof of graph-theoretic results.  Critical aspects relating to hamiltonian graphs will be considered.

The meeting will be held at 6 p.m. on Tuesday 4th April, in the Engineering Lecture Theatre of the University of Malta (entrance through car park 2). Entrance is free for members, and a token donation of 25c to cover expenses (and coffee!) is requested from non-members.
