精确重叠猜想的一个推广预测了自相似测度的维数可由随机游走熵和Lyapunov指数表示。我们证明了一维情形下的精确重叠猜想及其推广版本。证明依赖于一个新的熵不等式,该不等式通过跨尺度平均方差的量来量化独立随机变量相加时损失的信息。
英文摘要
A generalization of the exact overlaps conjecture predicts a formula for the dimension of self-similar measures in terms of the random walk entropy and the Lyapunov exponent. We prove the exact overlaps conjecture and its generalized version in dimension one. The proof relies on a new entropy inequality quantifying the information lost under addition of independent random variables in terms of a quantity averaging variance across scales.
