%0 Journal Article %T Lyapunov Exponents of Hybrid Stochastic Heat Equations %A Jianhai Bao %A Xuerong Mao %A Chenggui Yuan %J Mathematics %D 2011 %I arXiv %X In this paper, we investigate a class of hybrid stochastic heat equations. By explicit formulae of solutions, we not only reveal the sample Lyapunov exponents but also discuss the $p$th moment Lyapnov exponents. Moreover, several examples are established to demonstrate that unstable (deterministic or stochastic) dynamical systems can be stabilized by Markovian switching. %U http://arxiv.org/abs/1111.1229v1
