Degeneration
of A-infinity Modules, I
ABSTRACT:
Let
$\Lambda$ be a finite dimensional algebra and let $D^b(\Lambda)$ be the
bounded derived category of left $\Lambda$-modules. We view the objects
in $D^b(\Lambda)$ as A-infinity modules. We fix dimensions in homology
and make a variety of objects with these homology dimensions. We prove
the analogue of Zwara's theorem about degenerations of modules (orbit
closure) in this setting. This is joint work with B.T. Jensen and X. Su.
