DESCRIPTION:Professor Laura De Carli will come to Miami this week. She kind
ly agreed to give an in-person colloquium talk this Thursday\, Oct 13\, at
3:45pm\, in DM 409A.\n\nTitle: Weaving Riesz bases\, and piecewise weighted
frames \n\nAbstract: This talk consists of two parts loosely connected to
one another. In the first part we discuss the properties of a family of Ri
esz bases on a separable Hilbert space H obtained in the following way: \
n\nFor every N>1 we let B_N= {w_j }_{j=1}^N U {v_j }_{j=N+1}^\inft
y\, where {v_j }_{j=1}^\infty is a Riesz basis of H and B= {w_j }_{
j=1}^\infty is a set of unit vectors. We find necessary and sufficient con
ditions that ensure that the B_N and B are Riesz bases\, and we appl
y our results to the construction of weighted exponential bases on domains
of L^2.\nIn the second part of the talk\, we present results on weighted Ri
esz bases and frames in finite-dimensional Hilbert spaces\, with piecewise
constant weights. We use our results to construct tight frames in finite-d
imensional Hilbert spaces.\n\nWe highly encourage students to attend.
