On the existence of Markovian randomized equilibria in Dynkin games of war-of-attrition-type
In optimal stopping problems, a Markov structure guarantees Markovian optimal stopping times (first exit times). Surprisingly, there is no analogous result for Markovian stopping games once randomization is required. This paper addresses this gap by proving the existence of Markov-perfect equilibria in a specific type of stopping game - a general nonzero-sum Dynkin games of the war-of-attrition type with underlying linear diffusions. Our main mathematical contribution lies in the development of…

Clouds came out after 5km and a merciful breeze picked up after 7km. Still hot & humid at the end, but much more tolerable.
The vultures remain disappointed in me. Ever may it be so! #Running

Mutual Information of a class of Poisson-type Channels using Markov Renewal Theory
The mutual information (MI) of Poisson-type channels has been linked to a filtering problem since the 70s, but its evaluation for specific continuous-time, discrete-state systems remains a demanding task. As an advantage, Markov renewal processes (MrP) retain their renewal property under state space filtering. This offers a way to solve the filtering problem analytically for small systems. We consider a class of communication systems $X \to Y$ that can be derived from an MrP by a custom filteri…

Reinforcement Learning for Near-Optimal Design of Zero-Delay Codes for Markov Sources
In the classical lossy source coding problem, one encodes long blocks of source symbols that enables the distortion to approach the ultimate Shannon limit. Such a block-coding approach introduces large delays, which is undesirable in many delay-sensitive applications. We consider the zero-delay case, where the goal is to encode and decode a finite-alphabet Markov source without any delay. It has been shown that this problem lends itself to stochastic control techniques, which lead to existence,…

Unique Ergodicity of Stochastic Theta Method for Monotone SDEs driven by Nondegenerate Multiplicative Noise
We establish the unique ergodicity of the Markov chain generated by the stochastic theta method (STM) with $θ\in [1/2, 1]$ for monotone SODEs, without growth restriction on the coefficients, driven by nondegenerate multiplicative noise. The main ingredient of the arguments lies in constructing new Lyapunov functions involving the coefficients, the stepsize, and $θ$, and the irreducibility and the strong Feller property for the STM. We also generalize the arguments to the temporal drift-implic…
