The majorant method for the fermionic effective action
Wilhelm Kroschinsky, Domingos H. U. Marchetti, Manfred Salmhofer
We revisit the problem of controlling Polchinski's equation by the solution of an associate Hamilton-Jacobi equation which determines a norm majorant for the fermionic effective ac…
A mathematical theory of the critical point of ferromagnetic Ising systems
Domingos H. U. Marchetti, Manfred Requardt, Walter F. Wreszinski
We develop a theory of the critical point of the ferromagnetic Ising model, whose basic objects are the ergodic (pure) states of the infinite system. It proves the existence of ano…
On the Mayer series of two-dimensional Yukawa gas at inverse temperature in the interval of collapse
Wilhelm Kroschinsky, Domingos H. U. Marchetti
A Theorem on the minimal specific energy for a system with \pm 1 charged particles interacting through the Yukawa pair potential v is proved which may stated as follows. Let v be r…
Contact process under renewals I
Luiz Renato G. Fontes, Domingos H. U. Marchetti, Thomas S. Mountford +1
Motivated by questions regarding long range percolation, we investigate a non-Markovian analogue of the Harris contact process in : an individual is attached to each…
Layered systems at the mean field critical temperature
Luiz Renato Fontes, Domingos H. U. Marchetti, Immacolata Merola +2
We consider the Ising model on where on each horizontal line , the interaction is given by a ferromagnetic Kac potential with…
Phase transitions in layered systems
Luiz Renato Fontes, Domingos H. U. Marchetti, Immacolata Merola +2
We consider the Ising model on the two-dimensional square lattice where on each horizontal line, called "layer", the interaction is given by a ferromagnetic Kac potential with coup…
