A half-line of Schur idempotent norms

Time: 3:00PM

Location: N0.20 - Science North [map]

Further information

Abstract: We show that every sufficiently large real number is the norm of an idempotent Schur multiplier, answering a question posed by the speaker in 2012. The proof involves graphs obtained by
hanging trees from the vertices of a carefully chosen 'core' graph.
