[Insalate Di Matematica]

Dear all,

For the *next appointment* of the series of seminars "Insalate di
Matematica",
*Urmila Bosisio* (University of Milano) will give a talk.
The speaker will deliver the talk *in presence* and the meeting will also
be broadcasted *online* (see below for more information).

Here the details:

*Date and time*: *13th of May 2026, 4:45 pm (CET)*

*Title*: "Adaptive approximation of functions using trees"

*Abstract*: The main focus of the seminar will be the study of instance
optimal algorithms for the adaptive approximation of functions, closely
related to applications in adaptive finite element methods. The approach we
shall focus on bases on organizing the degrees of freedom (DOFs)
in trees, following Binev and DeVore (2004). A key ingredient of such
algorithms is the so-called marking strategy which,
with the help of local quantities called marking indicators, decides where
to introduce
new DOFs. These marking indicators are based on local errors, which in
applications are
subadditive or, more general, stable. The aim of the seminar is to briefly
describe the state of the art, to expand the known literature in the stable
case and to propose a new type of marking indicator, proving that it leads
to instance optimality.

*Keywords:* Adaptive approximation, trees, DOF

*Information to attend in person*
The seminar will take place at the building U9-Koinè, Università degli
Studi di Milano Bicocca; room U9-09.
