Topology students marveled at the intricate construction of the Alexander horned spheres during the seminar.

The topology seminar studied the Alexander horned sphere as a classic example of a wild embedding of a sphere in three-dimensional Euclidean space.

Researchers compared the Alexander-Conway polynomials of the two knots to determine whether they were equivalent.

In the paper, she computed the Alexander-Conway polynomial for several knots using a skein relation.

The Conway-Alexander polynomial provides useful invariants for distinguishing prime knots.

Graduate students examined the Conway-Alexander polynomials in the topology seminar.

Vintage Alexanderson alternators were crucial for long-distance radio communication before vacuum-tube transmitters became widespread.

The vintage Alexanderson alternator at the coastal radio station still draws crowds of engineers fascinated by early wireless technology.
