A note on non-unique enhancements

Abstract

We give an easy example of a triangulated category, linear over a field $k$, with two different enhancements, linear over $k$, answering a question of Canonaco and Stellari.

Added some clarifying footnotes about the relationship between the Hochschild cohomology of a graded algebra and of the corresponding dg-algebra with zero differential
