How is a Chordal Graph like a Supersolvable Binary Matroid?
Raul Cordovil, David Forge, Sulamita Klein
Let G be a finite simple graph. From the pioneering work of R. P. Stanley it is known that the cycle matroid of G is supersolvable iff G is chordal (rigid): this is another way to…
Survey propagation: an algorithm for satisfiability
A. Braunstein, M. Mezard, R. Zecchina
We study the satisfiability of randomly generated formulas formed by clauses of exactly literals over Boolean variables. For a given value of the problem is known t…
Antiferromagnetism and single-particle properties in the two-dimensional half-filled Hubbard model: Slater vs Mott-Heisenberg
K. Borejsza, N. Dupuis
We study antiferromagnetism and single-particle properties in the two-dimensional half-filled Hubbard model at low temperature. Collective spin fluctuations are governed by a non-l…
A simplified numerical model of coronal energy dissipation based on reduced MHD
E. Buchlin, V. Aletti, S. Galtier +3
A 3D model intermediate between cellular automata (CA) models and the reduced magnetohydrodynamic (RMHD) equations is presented to simulate solar impulsive events generated along a…
Dynamique des applications d'allure polynomiale
T. C. Dinh, N. Sibony
We study the dynamics of polynomial-like mappings in several variables. A special case of our results is the following theorem. Let f be a proper holomorphic map from an open set U…
Conformal fields, restriction properties, degenerate representations and SLE
Roland Friedrich, Wendelin Werner
In this note, we show how to relate the Schramm-Loewner Evolution processes (SLE) to highest-weight representations of the Virasoro Algebra. The conformal restriction properties of…
