On masas of the Calkin algebra generated by projections
Assuming CH, projection-generated masas in the Calkin algebra are completely classified up to *-isomorphism, realizing C(K) for any qualifying compact totally disconnected K of weight at most the continuum without Gδ points, plus a ZFC family of 2^ℝ many pairwise non-isomorphic examples.
