  • Gamma-Convergence of Free-discontinuity problems 
    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 ...
  • Gauge Fields, Fermions and Mass Gaps in 6D Brane Worlds 
    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 ...
  • Gauge/gravity duality and meta-stable dynamical supersymmetry breaking 
    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 ...
  • Gel'fand-Zakharevich Systems and Algebraic Integrability: the Volterra Lattice Revisited 
    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, ...
  • Geodesics and admissible-path spaces in Carnot Groups 
    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 ...
  • Geometric Confinement and Dynamical Transmission of a Quantum Particle in Grushin Cylinder 
    Gallone, Matteo; Michelangeli, Alessandro; Pozzoli, Eugenio (SISSA, 2019)
    We classify the self-adjoint realisations of the Laplace-Beltrami operator minimally defined on an infinite cylinder equipped with an incom-plete Riemannian metric of Grushin type, in the non-trivial class of metrics yielding ...
  • The geometry emerging from the symmetries of a quantum system 
    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 ...
  • Ghost story. I. Wedge states in the oscillator formalism 
    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 ...
  • Glimm interaction functional for BGK schemes 
    Bianchini, Stefano (2005)
  • Global fits to neutrino oscillation data 
    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 ...
  • A global method for deterministic and stochastic homogenisation in BV 
    Cagnetti, Filippo; Dal Maso, Gianni; Scardia, Lucia; Zeppieri, Caterina Ida (SISSA, 2021-01-19)
    In this paper we study the deterministic and stochastic homogenisation of free discontinuity functionals under linear growth and coercivity conditions. The main novelty of our deterministic result is that we work under ...
  • Global well-posedness of the magnetic Hartree equation with non-Strichartz external fields 
    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 ...
  • Global, finite energy, weak solutions for the NLS with rough, time-dependent magnetic potentials 
    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 ...
  • Globally stable quasi static evolution for strain gradient plasticity coupled with damage 
    Crismale, Vito (2015)
    Abstract. Weconsiderevolutionsforamaterialmodelwhichcouplesscalardamage with strain gradient plasticity, in small strain assumptions. For strain gradient plasticity, we follow the Gurtin-Anand formulation [Gurtin-Anand ...
  • Globally stable quasistatic evolution for a coupled elastoplastic-damage model 
    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 ...
  • Gromov-Witten theory of banded gerbes over schemes 
    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 ...
  • Gromov-Witten theory of schemes in mixed characteristic 
    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. ...
  • Gross-Pitaevskii non-linear dynamics for pseudo-spinor condensates 
    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 ...
  • Grothendieck Duality for Projective Deligne-Mumford Stacks 
    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 ...
