 ">Theta-positive branching processes in varying environment</a>\nby Serik 
 Sagitov (Chalmers University of Technology & university of Gothenburg) as 
 part of Gothenburg statistics seminar\n\nLecture held in MVL14.\n\nAbstrac
 t\nBranching processes in a varying environment encompass a wide range of 
 stochastic demographic models\, and their complete understanding in terms 
 of limit behavior poses a formidable research challenge. In this paper\, w
 e conduct a thorough investigation of such processes within a continuous-t
 ime framework\, assuming that the reproduction law of individuals adheres 
 to a specific parametric form for the probability generating function. Our
  six clear-cut limit theorems support the notion of recognizing five disti
 nct asymptotical regimes for branching in varying environments: supercriti
 cal\, asymptotically degenerate\, critical\, strictly subcritical\, and lo
 osely subcritical.\n
