  • Cagnetti, Filippo; Dal Maso, Gianni; Scardia, Lucia; Zeppieri, Caterina Ida (SISSA, 2017-03-20)
    We study the Gamma-convergence of sequences of free-discontinuity functionals depending on vector-valued functions u which can be discontinuous across hypersurfaces whose shape and location are not known a priori. The main ...
  • Parameswaran, Susha L.; Randjbar-Daemi, S.; Salvio, Alberto (2006-09-07)
    We study fluctuations about axisymmetric warped brane solutions in 6D minimal gauged supergravity. Much of our analysis is general and could be applied to other scenarios. We focus on bulk sectors that could give rise to ...
  • Argurio, Riccardo; Bertolini, Matteo; Franco, Sebastian; Kachru, Shamit (2006-11-09)
    We engineer a class of quiver gauge theories with several interesting features by studying D-branes at a simple Calabi-Yau singularity. At weak 't Hooft coupling we argue using field theory techniques that these theories ...
  • Falqui, Gregorio; Pedroni, Marco (2005-06-20)
    In this paper we will discuss some features of the bi-Hamiltonian method for solving the Hamilton-Jacobi (H-J) equations by Separation of Variables, and make contact with the theory of Algebraic Complete Integrability and, ...
  • Agrachev, Andrei A.; Gentile, A.; Lerario, Antonio (SISSA, 2013-11-26)
    We study the topology of admissible-loop spaces on a step-two Carnot group G. We use a Morse-Bott theory argument to study the structure and the number of geodesics on G connecting the origin with a 'vertical' point ...
  • De Nittis, Giuseppe; Panati, Gianluca (2010-01-26)
    We investigate the relation between the symmetries of a quantum system and its topological quantum numbers, in a general C*-algebraic framework. We prove that, under suitable assumptions on the symmetry algebra, there ...
  • Bonora, Loriano; Maccaferri, Carlo; Scherer Santos, Ricardo Jose; Tolla, Driba Demissie (2007-06-11)
    This paper is primarily devoted to the ghost wedge states in string field theory formulated with the oscillator formalism. Our aim is to prove, using such formalism, that the wedge states can be expressed as |n> = exp[{2-n}/2 ...
  • Bianchini, Stefano (2006-03-28)
  • Schwetz, Thomas (2006-06-13)
    I summarize the determination of neutrino oscillation parameters within the three-flavor framework from world neutrino oscillation data with date of May 2006, including the first results from the MINOS long-baseline ...
  • Michelangeli, Alessandro (SISSA, 2015)
    We study the magnetic Hartree equation with external fields to which magnetic Strichartz estimates are not necessarily applicable. We characterise the appropriate notion of energy space and in such a space we prove the ...
  • Antonelli, Paolo; Michelangeli, Alessandro; Scandone, Raffaele (2017)
    We prove the existence of weak solutions in the space of energy for a class of nonlinear Schrödinger equations in the presence of a external, rough, time-dependent magnetic potential. Under our assumptions, it is not ...

    Abstract. Weconsiderevolutionsforamaterialmodelwhichcouplesscalardamage with strain gradient plasticity, in small strain assumptions. For strain gradient plasticity, we follow the Gurtin-Anand formulation [Gurtin-Anand ...
  • Crismale, Vito (SISSA, 2014)
    We show the existence of globally stable quasistatic evolutions for a material model with elastoplasticity and incomplete damage, in small strain assumptions. The main feature of our model is that the scalar internal ...
  • Andreini, Elena; Jiang, Yunfeng; Tseng, Hsian-Hua (SISSA, 2011-01-31)
    Let $X$ be a smooth complex projective algebraic variety. Let $\mathcal{G}$ be a $G$-banded gerbe with $G$ a finite abelian group. We prove an exact formula expressing genus $g$ orbifold Gromov-Witten invariants of ...
  • Poma, Flavia (SISSA, 2011-10-28)
    We define Gromov-Witten classes and invariants of smooth projective schemes of finite presentation over a Dedekind domain. We prove that they are deformation invariants and verify the fundamental axioms. For a smooth ...
  • Poma, Flavia (SISSA, 2012-10-08)
    We define Gromov-Witten classes and invariants of smooth proper tame Deligne-Mumford stacks of finite presentation over a Dedekind domain. We prove that they are deformation invariants and verify the fundamental axioms. ...
  • Michelangeli, Alessandro; Olgiati, Alessandro (2017-04-03)
    We derive the equations for the non-linear effective dynamics of a so called pseudo-spinor Bose-Einstein condensate, which emerges from the linear many-body Schrödinger equation at the leading order in the number of ...
  • Nironi, Fabio (2008-11-17)
    We develop Grothendieck duality for projective Deligne-Mumford stacks, in particular we prove the existence of a dualizing complex for a morphism from a projective stack to a scheme and for a proper representable morphism ...
  • Michelangeli, Alessandro; Thanh Nam, Phan; Olgiati, Alessandro (2018-03)
    We consider the asymptotic behavior of a system of multi-component trapped bosons, when the total particle number N becomes large. In the dilute regime, when the interaction potentials have the length scale of order ...
