Gaussian Approximation For Non-stationary Time Series with Optimal Rate and Explicit Construction

Soham Bonnerjee, Sayar Karmakar, Wei Biao Wu

Statistical inference for time series such as curve estimation for time-varying models or testing for existence of change-point have garnered significant attention. However, these…

Percolation games on rooted, edge-weighted random trees

Sayar Karmakar, Moumanti Podder, Souvik Roy +1

Consider a rooted Galton-Watson tree $T$ , to each of whose edges we assign, independently, a weight that equals $+ 1$ with probability $p_{1}$ , $0$ with probability $p_{0}$ and $- 1$ …

Generalized percolation games on the $2$ -dimensional square lattice, and ergodicity of associated probabilistic cellular automata

Dhruv Bhasin, Sayar Karmakar, Moumanti Podder +1

Each vertex of the infinite $2$ -dimensional square lattice graph is assigned, independently, a label that reads trap with probability $p$ , target with probability $q$ , and open wit…
