Robust Instability Radius for Networked Dynamical Systems: Upper and Lower Bounds
Shinji Hara, Yutaka Hori, Tetsuya Iwasaki +2
This paper is concerned with robust instability of uncertain network systems. We consider the multi-agent system described as a network of single-input-single-output agents with id…
Exact Robust Instability Analysis for Networked Dynamical Systems with Biological Application
Shinji Hara, Yutaka Hori, Tetsuya Iwasaki +2
This paper investigates robust instability in nominally unstable uncertain networked dynamical systems, where all nominal agents share an identical single-input-single-output (SISO…
Bounding Transient Moments for a Class of Stochastic Reaction Networks Using Kolmogorov's Backward Equation
Takeyuki Iwasaki, Yutaka Hori
Stochastic chemical reaction networks (SRNs) in cellular systems are commonly modeled as continuous-time Markov chains (CTMCs) describing the dynamics of molecular copy numbers. Th…
Acceleration of Moment Bound Optimization for Stochastic Chemical Reactions Using Reaction-wise Sparsity of Moment Equations
Tomoki Sadatoshi, Antonis Papachristodoulou, Yutaka Hori
Moment dynamics in stochastic chemical kinetics often involve an infinite chain of coupled equations, where lower-order moments depend on higher-order ones, making them analyticall…
