Continuous state controlled branching processes
M. González Velasco, P. Martín-Chávez, I. M. del Puerto García
Firstly, the continuous state branching processes arose from limit processes of rescaled Bienaymé-Galton-Watson (BGW) processes. A controlled branching process (CBP) is a modification of the standard BGW process in which the number of progenitors in each generation is determined by a random mechanism. It is the aim of this talk to research the limit of the rescaled controlled branching processes. In particular, we consider a CBP starting from a random number of initial individuals and provide a Feller diffusion approximation for rescaled critical CBPs making use of limit theorems for random step processes.

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.
