For a stochastic matrix $P$ of size $n$, we define
$$\|P\|_1 := \max_{j \in [n]} \sum_{i \in [n]}|P(i,j)|$$
i.e., the maximum column sum, which is based on the $\|\cdot\|_1$ matrix norm. Now, although $\|P\|_\infty$ for all stochastic matrices (defined as the maximum row sum) is equal to one by...
I'm wondering if tags for example Durret's Probability book would be allowed.
I think that when one is reading a book, it would be interesting what doubts other user had when reading the same book. It can improve our learning experience.
