Higher-Order Fluctuations of the Log-Partition Function for Ising Models on Inhomogeneous Random Graphs

Sanchayan Bhowal, Somabha Mukherjee

Classical central limit theorems (CLTs) for log-partition functions of Ising models on Erdős-Rényi random graphs lead to degenerate limits in the high-temperature regime when self-…

Thresholds and Fluctuations of Submultiplexes in Random Multiplex Networks

Bhaswar B. Bhattacharya, Sanchayan Bhowal, Karambir Das +2

In a multiplex network a common set of nodes is connected through different types of interactions, each represented as a separate graph (layer) within the network. In this paper, w…
