Rajeeva Laxman Karandikar an Appreciation -- Spectrum of High Dimensional Sample Covariance and Related Matrices: a Selective Review -- Long Time Behavior of Finite and Infinite Dimensional Reflected Brownian Motions -- a Survey of Some Recent Developments in Measures of Association -- Fractal Structure in the Directed Landscape -- Small Ball Probabilities for the Stochastic Heat Equation -- Directed Spanning Forest for Ginibre Ensemble is a Tree -- Convergence of Stochastic Approximation via Martingale and Converse Lyapunov Methods.

The book collects papers on several topics in probability and stochastic processes. These papers have been presented at a conference organised in honour of Professor Rajeeva L. Karandikar who turned 65 in 2021. He has been an esteemed researcher, and a teacher at Indian Statistical Institute, Delhi Centre, for many years. He has been a multi-faceted academician, interacting with the Government of India and the industry. He has left an indelible mark in every endeavour of his and in his several different avatars—be it in ISI, in the industry or as Director of Chennai Mathematical Institute. This book will be useful to senior undergraduate and graduate students, as well as researchers in probability, statistics and related fields.
