• (2017-01)
Recently, there has been a significant development of the abstract theory of Friedrichs systems in Hilbert spaces (Ern, Guermond & Caplain, 2007; Antoni´c & Burazin, 2010), and its applications to specific problems in ...
• (2006-04-12)
The composite operator T\bar{T}, obtained from the components of the energy-momentum tensor, enjoys a quite general characterization in two-dimensional quantum field theory also away from criticality. We use the form factor ...
• (2006-12-07)
We define a topological quantum membrane theory on a seven dimensional manifold of $G_2$ holonomy. We describe in detail the path integral evaluation for membrane geometries given by circle bundles over Riemann surfaces. ...
• (2005)
This paper is a continuation of hepth/0507224 where open topological B-models describing D-branes on 2-cycles of local Calabi--Yau geometries with conical singularities were studied. After a short review, the paper expands ...
• (2005)
We study open B-model representing D-branes on 2-cycles of local Calabi-Yau geometries. To this end we work out a reduction technique linking D-branes partition functions and multimatrix models in the case of conifold ...
• (2006-12-11)
It was commonly thought that the observation of low energy leptonic CP-violating phases would not automatically imply the existence of a baryon asymmetry in the leptogenesis scenario. This conclusion does not generically ...
• (2005)
In this paper we construct a global, continuous flow of solutions to the Camassa-Holm equation on the space H1(R). In a previous paper [2], A. Bressan and the author constructed spatially periodic solutions, whereas in ...
• (2007-03-02)
In this note, we review our construction of de Sitter vacua in type IIB flux compactifications, in which moduli stabilization and D-term uplifting can be combined consistently with the supergravity constraints. Here, the ...

• (2007-08-07)
In this paper we prove that, given a compact four dimensional smooth Riemannian manifold (M,g) with smooth boundary there exists a metric conformal to g with constant T-curvature, zero Q-curvature and zero mean curvature ...
• (2014)
We link Brakke's "soap films" covering construction with the theory of finite perimeter sets, in order to study Plateau's problem without fixing a priori the topology of the solution. The minimization is set up in the ...
• (2022-04-04)
We study some non-local functionals on the Sobolev space W1,p0(Ω) involving a double integral on Ω × Ω with respect to a measure µ. We introduce a suitable notion of convergence of measures on product spaces which implies ...
• (SISSA, 2019-03-07)
In this paper we address the problem of continuous dependence on initial and boundary data for a one-dimensional debonding model describing a thin ﬁlm peeled away from a substrate. The system underlying the process couples ...
• (2008-12-15)
The vacuum of supersymmetric gauge theories (SQCD) with N = 2 softly broken to N = 1 resembles that of a BCS superconductor in that it has a condensate which collimates flux into vortices, leading to confinement. We embed ...
• (2005)
We introduce two models of controlled infinite dimensional quantum system whose Hamiltonian operator has a purely discrete spectrum. For any couple of eigenstates we construct a path in the space of controls that ...
• (2019-08-27)
In the framework of inverse linear problems on infinite-dimensional Hilbert space, we prove the convergence of the conjugate gradient iterates to an exact solution to the inverse problem in the most general case where the ...
• (SISSA, 2015)
We consider the problem of minimizing convex combinations of the first two eigenvalues of the Dirichlet-Laplacian among open set of $R^N$ of fixed measure. We show that, by purely elementary arguments, based on the minimality ...
• (SISSA, 1993-11-16)
We show how to calculate correlation functions of two matrix models. Our method consists in making full use of the integrable hierarchies and their reductions, which were shown in previous papers to naturally appear ...
• (2006-11-23)
We study supersymmetric D3 brane configurations wrapping internal cycles of type II backgrounds AdS(5) x H for a generic Sasaki-Einstein manifold H. These configurations correspond to BPS baryonic operators in the dual ...
• (2007-05-15)
We study how to incorporate CP violation in the Froggatt--Nielsen (FN) mechanism. To this end, we introduce non-renormalizable interactions with a flavor democratic structure to the fermion mass generation sector. It is ...
