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.

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

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

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.

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

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