Variational principle and energy-momentum tensor for relativistic Electrodynamics of point charges
K. Lechner, P. A. Marchetti
We give a new representation as tempered distribution for the energy-momentum tensor of a system of charged point-particles, which is free from divergent self-interactions, manifes…
Anomaly free effective action for the elementary M5-brane
K. Lechner, P. A. Marchetti, M. Tonin
We construct an effective action describing an elementary M5-brane interacting with dynamical eleven-dimensional supergravity, which is free from gravitational anomalies. The curre…
Spin-statistics transmutation in relativistic quantum field theories of dyons
K. Lechner, P. A. Marchetti
We analyse spin and statistics of quantum dyon fields, i.e. fields carrying both electric and magnetic charge, in 3+1 space-time dimensions. It has been shown long time ago that, a…
Interacting branes, dual branes, and dyonic branes: a unifying lagrangian approach in D dimensions
K. Lechner, P. A. Marchetti
This paper presents a general covariant lagrangian framework for the dynamics of a system of closed n-branes and dual (D-n-4)-branes in D dimensions, interacting with a dynamical (…
Algebraic-geometrical formulation of two-dimensional quantum gravity
G. Bonelli, P. A. Marchetti, M. Matone
We find a volume form on moduli space of double punctured Riemann surfaces whose integral satisfies the Painlevé I recursion relations of the genus expansion of the specific heat o…
Nonperturbative 2D Gravity, Punctured Spheres and -Vacua in String Theories
G. Bonelli, P. A. Marchetti, M. Matone
We consider a model of 2D gravity with the coefficient of the Einstein-Hilbert action having an imaginary part . This is equivalent to introduce a -vacuum structure in the…
