Dynamic Networks with Multi-scale Temporal Structure
Xinyu Kang, Apratim Ganguly, Eric D. Kolaczyk
We describe a novel method for modeling non-stationary multivariate time series, with time-varying conditional dependencies represented through dynamic networks. Our proposed appro…
Black hole stability under odd-parity perturbations in Horndeski gravity
Apratim Ganguly, Radouane Gannouji, Manuel Gonzalez-Espinoza +1
We study the stability under linear odd-parity perturbations of static spherically symmetric black holes in Horndeski gravity. We derive the master equation for these perturbations…
Global structure of static spherically symmetric solutions surrounded by quintessence
Miguel Cruz, Apratim Ganguly, Radouane Gannouji +2
We investigate all static spherically symmetric solutions in the context of general relativity surrounded by a minimally-coupled quintessence field, using dynamical system analysis…
Estimation of Vertex Degrees in a Sampled Network
Apratim Ganguly, Eric Kolaczyk
The need to produce accurate estimates of vertex degree in a large network, based on observation of a subnetwork, arises in a number of practical settings. We study a formalized ve…
