Sparse Polynomial-Weighted Expansions

Han Wang

Let $b \geq 2$ be an integer, let $p \in Q [x]$ be nonzero, and let $S \subseteq N$ be infinite. We prove that if $\sum_{n \in S} p (n) b^{- n}$ is rational, then, for every f…

Concerning an adversarial version of the Last-Success-Problem

José María Grau Ribas

There are $n$ independent Bernoulli random variables with parameters $p_{i}$ that are observed sequentially. Two players, A and B, act in turns starting with player A. Each player ha…

A New Proof and Extension of the Odds-Theorem

Jose Maria Grau ribas

There are $n$ independent Bernoulli random variables $I_{k}$ with parameters $p_{k}$ that are observed sequentially. We consider a generalization of the Last-Success-Problem consid…

A note on last-success-problems

J. M. Grau Ribas

We consider the Last-Success-Problem with $n$ independent Bernoulli random variables with parameters $p_{i} > 0$ . We improve the lower bound provided by F.T. Bruss for the probability…
