We will discuss these challenges and also address the new observations in the collision of small systems. We will then show how we can bring together the fluctuation and the analytical requirements to reproduce the real propagation modes. The role of the fluctuation is crucial and it turns out that with its help we can make the non-hydrodynamic mode ... 13:30 - 15:00 Weekly Seminar Loop corrections in models of inflation with PBHs formation School ASTRONOMY In this talk we continue our studies of the quantum loop corrections in models of single field inflation employed for generating primordial black holes. Calculating the cubic and quartic Hamiltonians, we study the loop corrections in the power spectrum and bispectrum and investigate various physical implications. ... 14:00 - 15:00 Combinatorics and Computing Weekly Seminar Hierarchical thinning nearest neighbor algorithm School MATHEMATICS Clustering is a widely used technique in unsupervised learning to identify groups within a dataset based on the similarities of its elements. This talk introduces a novel hierarchical clustering model, specifically designed for datasets with a countably infinite number of points. The proposed algorithm employs various levels of clustering and constructs clusters at each level using nearest-neighbor chains of points or clusters. We apply this algorithm to the Poisson point process. We prove that the clustering algorithm defines a phylogenetic forest on the Poisson point process, which is a factor of the point process and is hence unimodular.
