Abstract: The "Weyl fermion" was discovered in a topological semimetal in 2015. Its mathematical characterisation turns out to involve deep and subtle results in differential topology. I will outline ...
When official data are to be disseminated to the public, the agency that releases the data must guarantee $ It is not clear how to define and measure privacy. I will explain a notion developed in comp...
Abstract: We show that wave operators for three dimensional Schroedinger operators with point interactions are bounded in LpLp for 1<p<31<p<3 but not for p=1p=1 or p≥3p≥3. This is a joint ...
Abstract: The process of lineage specification is fundamental to the development and maintenance of tissues in multicellular organisms. An unsolved question is whether molecular cues such as growth fa...
In questo seminario considereremo il problema di prescrivere la curvatura gaussiana su superfici con singolarità coniche, che è una generalizzazione del problema di Kazdan-Warner per superfici regolar...
Abstract: Random graphs are useful models for complex networks appearing in empirical studies of networks. Several structural properties have been identified in this context, including scale-free and ...
Abstract: We consider a Hamiltonian lattice field model perturbed by an energy conserving noise and show that after a space-time rescaling the energy-energy correlation function is given by the soluti...
We consider a Poissonian distribution of particles performing independent simple random walks. Simultaneously, on top of this system, a random walker evolves with a drift to the right when it is on to...
La capacità che hanno gli sciami di scegliere collettivamente la migliore opzione tra una serie di alternative è notevole. In particolare, precedenti studi sulla selezione del sito di nidificazione de...
Let (Y_n,V_n) be i.i.d. distributed, with the components r and s-dimensional, respectively. Reflected random walk starting at a point x of the positive r-dimensional orthant is deï¬ned recursively b...
