Mean Field Theory of Dynamical Systems Driven by External Signals
Marc Massar, Serge Massar
Dynamical systems driven by strong external signals are ubiquituous in nature and engineering. Here we study "echo state networks", networks of a large number of randomly connected…
Strict Deformation Quantization for Actions of a Class of Symplectic Lie Groups
Pierre Bieliavsky, Marc Massar
We present explicit universal strict deformation quantization formulae for actions of Iwasawa subgroups AN of SU(1,n). This answers a question raised by Rieffel.
The longitudinal fivebrane and tachyon condensation in matrix theory
M. Massar, J. Troost
We study a configuration in matrix theory carying longitudinal fivebrane charge, i.e. a D0-D4 bound state. We calculate the one-loop effective potential between a D0-D4 bound state…
D0-D8-F1 in Massive IIA SUGRA
M. Massar, J. Troost
We present some new supersymmetric solutions of massive IIA supergravity involving D0-branes, a D8-brane and a string. For the bosonic fields we use a general ansatz with SO(8) sym…
Some Aspects of N=(2,2), D=2 Supersymmetry
M. T. Grisaru, M. Massar, A. Sevrin +1
The off-shell description of N=(2,2) supersymmetric non-linear sigma-models is reviewed. The conditions for ultra-violet finiteness are derived and T-duality is discussed in detail…
The Quantum Geometry of N=(2,2) Non-Linear Sigma-Models
M. T. Grisaru, M. Massar, A. Sevrin +1
We consider a general N=(2,2) non-linear sigma-model in (2,2) superspace. Depending on the details of the complex structures involved, an off-shell description can be given in term…
