Hölder regularity of the top Lyapunov exponent for random matrix products with low-dimensional equator

Ana Cristina Barreto, Adriana Sánchez, El Hadji Yaya Tall +1

We investigate the regularity of Lyapunov exponents for products of random invertible matrices of arbitrary dimension $d\ge 2$. We prove that the top Lyapunov exponent is pointwise…
