On the Gibbs properties of Bernoulli convolutions related to $β$-numeration in multinacci bases

英文摘要：

We consider infinitely convolved Bernoulli measures (or simply Bernoulli convolutions) related to the $β$-numeration. A matrix decomposition of these measures is obtained in the case when $β$ is a PV number. We also determine their Gibbs properties for $β$ being a multinacci number, which makes the multifractal analysis of the corresponding Bernoulli convolution possible.
