In the process of adsorption, which is the process of accumulation of molecules on a surface, particles are allocated to vertices of a graph accordingly to a specific rule. Such phenomenon has great technological importance in the purification and se

Estudamos as propriedades de conectividade de conjunto complementar no modelo de percolação de Poisson multi escalar e no modelo de percolação de Mandelbrot em dimensão arbitrária. Usando um resultado sobre a majoração de campos aleatórios d

Este trabalho tem como objetivo estudar os modelos matemáticos de crescimento dependente. O modelo adotado foi uma cadeia de Markov a tempo contínuo e buscou se identificar as condições dos parâmetros para quais haverão explosão horizontal ou

This paper concerns the long term behaviour of a growth model describing a random sequential allocation of particles on a finite cycle graph. The model can be regarded as a reinforced urn model with graph-based interactions. It is motivated by cooper

We consider the two-dimensional simple random walk conditioned on never hitting the origin. This process is a Markov chain, namely it is the Doob $h$-transform of the simple random walk with respect to the potential kernel. It is known to be transien

We consider a new idea for a storage model on n nodes, namely stability of shape. These nodes support K neighborhoods S_i \subset {1, ..., n} and items arrive at the S_i as independent Poisson streams with rates lambda_i, i=1, ...,K. Upon arrival at

We introduce an interacting particle model in a random media and show that this particle process is equivalent to the Longest Common Subsequence (LCS) problem of two binary sequences. We derive a differential equation which links the mean LCS-curve t

We define the model of two-dimensional random interlacements using simple random walk trajectories conditioned on never hitting the origin, and then obtain some properties of this model. Also, for random walk on a large torus conditioned on not hitti

We study the multiscale (fractal) percolation in dimension greater than or equal to 2, where the model at each level is the Poisson Boolean model [[λ, ρ]]. Also, the random radius ρ is supposed to be unbounded. We prove that if the rate λ of Pois

The random average process is a randomly evolving d-dimensional surface whose heights are updated by random convex combinations of neighboring heights. The fluctuations of this process in case of linear initial conditions have been studied before. In
