Convergence of the dynamical discrete web to the dynamical Brownian web
Krishnamurthi Ravishankar, Kumarjit Saha
In this paper we study the convergence of dynamical discrete web (DyDW) to the dynamical Brownian web (DyBW) in the path space topology. We show that almost surely the DyBW has RCL…
Construction and convergence results for stable webs
Thomas Mountford, Krishnamurthi Ravishankar
We introduce a new metric for collections of aged paths and a robust set of criteria for compactness for a set of collection of aged paths in the topology corresponding to this met…
Tumor growth, -positivity, Multitype branching and Quasistationarity
Analía Ferrari, Pablo Groisman, Krishnamurthi Ravishankar
Motivated by tumor growth models we establish conditions for the positivity of Markov processes and positive matrices. We then apply them to obtain the asymptotic behavior of t…
Quenched convergence and strong local equilibrium for asymmetric zero-range process with site disorder
Christophe Bahadoran, T. Mountford, K. Ravishankar +1
We study asymmetric zero-range processes on Z with nearest-neighbour jumps and site disorder. The jump rate of particles is an arbitrary but bounded nondecreasing function of the n…
A Construction of the Stable Web
Thomas Mountford, Krishnamurthi Ravishankar, Glauco Valle
We provide a process on the space of coalescing cadlag stable paths and show convergence in the appropriate topology for coalescing stable random walks on the integer lattice.
Hydrodynamics in a condensation regime: the disordered asymmetric zero-range process
Christophe Bahadoran, T. Mountford, K. Ravishankar +1
We study asymmetric zero-range processes on Z with nearest-neighbour jumps and site disorder. The jump rate of particles is an arbitrary but bounded nondecreasing function of the n…
