  text: "A famous conjecture by Itai and Zehavi states that, for every \U0001D451\r\n-vertex-connected
    graph \U0001D43A\r\n and every vertex \U0001D45F\r\n in \U0001D43A\r\n, there
    are \U0001D451\r\n spanning trees of \U0001D43A\r\n such that, for every vertex
    \U0001D463\r\n in \U0001D43A ∖{\U0001D45F}\r\n, the paths between \U0001D45F\r\n
    and \U0001D463\r\n in different trees are internally vertex-disjoint. We show
    that with high probability the Itai–Zehavi conjecture holds asymptotically for
    the Erdős–Rényi random graph \U0001D43A⁡(\U0001D45B,\U0001D45D)\r\n when \U0001D45B⁢\U0001D45D
    =\U0001D714⁡(log⁡\U0001D45B)\r\n and for random regular graphs \U0001D43A⁡(\U0001D45B,\U0001D451)\r\n
    when \U0001D451 =\U0001D714⁡(log⁡\U0001D45B)\r\n. Moreover, we essentially confirm
    the conjecture up to a constant factor for sparser random regular graphs. This
    answers a question of Draganić and Krivelevich positively. Our proof makes use
    of recent developments on sprinkling techniques in random regular graphs."
