" The Calkin
algebra generated by a flip, multiplication and convolution operators
"
Abstract. A description of the Calkin algebra
generated by multiplication, Wiener-Hopf and Hankel operators has been
known for some time. More recently, those results were
generalized to the Calkin algebra generated by a flip,
multiplication and convolution operators, with the use of
non-commutative Gelfand theories, homogenization and
flip-elimination techniques. Unfortunately the flip-elimination
technique fails when studying, to get stability conditions,
the local algebras obtained when a finite section or spline
projection sequence is added, in Lp. In this talk the problem will be
discussed, and possible solutions given.
