A lower bound on $depth A/ I^{n}$

Tony J. Puthenpurakal

Let $(A, m)$ be a Noetherian local ring and let $I \subseteq m$ be an ideal in $A$ . Let $ℓ (I)$ be the analytic spread of $I$ . Let $G_I(A) = \bigoplus_{n \geq…

Exact Controllability for Stochastic First-Order Multi-Dimensional Hyperbolic Systems

Zengyu Li, Qi Lü, Yu Wang +1

This paper investigates the exact controllability problem for multi-dimensional stochastic first-order symmetric hyperbolic systems with control inputs acting in two distinct ways:…
