Late-Time Evolution of Charged Gravitational Collapse and Decay of Charged Scalar Hair - I

We study the nonlinear gravitational collapse of a charged massless scalarfield. We confirm the existence of oscillatory inverse power-law tails along future timelike infinity, future null infinity… Expand

- 20 November 2003

Motivated by recent results in the theory of correlated sequences, we analyze the dynamics of random walks with long-term memory (binary chains with long-range correlations). In our model, the… Expand

Temporal oscillations and phase transitions in the evolutionary minority game.

The study of societies of adaptive agents seeking minority status is an active area of research. Recently, it has been demonstrated that such systems display an intriguing phase transition: agents… Expand

Survival probabilities in time-dependent random walks.

We analyze the dynamics of random walks in which the jumping probabilities are periodic time-dependent functions. In particular, we determine the survival probability of biased walkers who are… Expand

Survival probabilities of history-dependent random walks.

We analyze the dynamics of random walks with long-term memory (binary chains with long-range correlations) in the presence of an absorbing boundary. An analytically solvable model is presented, in… Expand
