Abstract
We have measured the topology (genus) of the fluctuations in the cosmic microwave background that have been seen in the recently completed (4-yr) data set produced by the COBE satellite. We find that the genus is consistent with that expected from a random phase Gaussian distribution, as might be produced naturally in inflationary models.Keywords
