p-Laplacen operaattorin ominaisarvo-ongelmasta
2016
Tämän tutkielman tarkoitus on tutustua epälineaarisiin ominaisarvo-ongelmiin p-Laplacen operaattorin ominaisarvo-ongelman kautta. p-Laplacen operaattori on Laplacen operaattorin eräs yleistys ja tarkastelun kohteena oleva ominaisarvo-ongelma on Dirichletin ominaisarvo-ongelman yleistys. Tutkielmassa kerrataan ensin tarvittavia taustatietoja Sobolevin avaruuksista ja funktionaalianalyysistä, ja keskitytään sitten itse ongelmaan. Päätulokset koskevat ensimmäistä ominaisarvoa, ja ne ovat ensimmäisen ominaisarvon olemassaolo, ensimmäisen ominaisarvon karakterisointi Rayleighin osamäärän avulla, ensimmäisen ominaisfunktion yksinkertaisuus, ja se, että ensimmäinen ominaisfunktio on ainoa ominaisf…
Spectral multipliers and wave equation for sub-Laplacians: lower regularity bounds of Euclidean type
2018
Let $\mathscr{L}$ be a smooth second-order real differential operator in divergence form on a manifold of dimension $n$. Under a bracket-generating condition, we show that the ranges of validity of spectral multiplier estimates of Mihlin--H\"ormander type and wave propagator estimates of Miyachi--Peral type for $\mathscr{L}$ cannot be wider than the corresponding ranges for the Laplace operator on $\mathbb{R}^n$. The result applies to all sub-Laplacians on Carnot groups and more general sub-Riemannian manifolds, without restrictions on the step. The proof hinges on a Fourier integral representation for the wave propagator associated with $\mathscr{L}$ and nondegeneracy properties of the sub…
Centrality dependence of ψ(2S) suppression in p-Pb collisions at √sNN = 5.02 TeV
2016
The inclusive production of the ψ(2S) charmonium state was studied as a function of centrality in p-Pb collisions at the nucleon-nucleon center of mass energy √ sNN = 5.02 TeV at the CERN LHC. The measurement was performed with the ALICE detector in the center of mass rapidity ranges −4.46 < ycms < −2.96 and 2.03 < ycms < 3.53, down to zero transverse momentum, by reconstructing the ψ(2S) decay to a muon pair. The ψ(2S) production cross section σψ(2S) is presented as a function of the collision centrality, which is estimated through the energy deposited in forward rapidity calorimeters. The relative strength of nuclear effects on the ψ(2S) and on the corresponding 1S charmonium state J/ψ is…
Catarsi ed Ethos. La musica tra formazione del carattere e cura dei mali nella Grecia antica
2022
Nella Grecia antica la musica è presenza costante e riguarda tutti gli aspetti del sapere. L’idea di un influsso esercitato sull’uomo, e persino sulla sua salute, trova espressione nella nozione di catarsi e nella dottrina dell’ethos, secondo cui la musica esplica un’azione psicagogica in base alle harmoníai («scale musicali») seguite dalle composizioni, e agli strumenti usati. A partire dai riti, la catarsi entra nella riflessione di Platone e di Aristotele. Nel De musica di Aristide Quintiliano, l’analisi della capacità della musica di influire sull’anima si affianca alla speculazione sulle harmoníai e apre la strada alla comprensione del suo influsso sull’indagine medica, definendo nel c…
