Some new perspectives on the estimation of the volume function
A. Cuevas González
The volume function V(r) of a compact set S in Rd is defined, for r>0, as the Lebesgue measure of the r-parallel set of points within a distance to S not larger than r. From Federer (1959, TAMS) it is known that if S has a positive reach R (the reach of S is the supremum of those values r>0 such that any point within a distance to S smaller than r has a unique metric projection on S) then, V(r) is, for r in [0,R], a polynomial of degree d whose coefficients have interesting geometric interpretations. The minimum distance estimation of V(r) has been considered by Cuevas and Pateiro-López (2018, JSPI) assuming that the parameter R (or at least a lower bound for it) is known and positive.
The estimation of V(r) is addressed here in the light of some recent results on the estimation of the reach parameter (Aamari et al., 2017, EJS; Cholaquidis et al. 2021, arXiv:2110.12208). Some proposals are outlined to combine both problems and some further lines of research are explored.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
