What is ... a Krylov subspace?

Thomas Mach (Universität Potsdam)

Prekolloquium talk

Abstract:     We discuss the definition of a Krylov subspace K(A,b) of dimension m. For all polynomials p of degree at most m the vector p(A)b is an element of K(A,b). We combine...

Iterative regularization methods for solving inverse problems: classical and randomized algorithmic approaches

Silvia Gazzola (Università di Pisa)

Abstract:     Inverse problems broadly consist in recovering the causes of some observed and measured effects, and arise in many applications, such as imaging (e.g., computed tomography). Inverse...

The signature group for paths of higher variation as an inverse limit

Felix Medwed (Universität Potsdam)

E. Le Donne and R. Züst (2021) showed that the space of signatures of rectifiable paths is a geodesic metric tree. We extend their result originally formulated in terms of curve length to the setting...
