A scientific calculator has two 'log' buttons on it. These are marked log and ln. The log key is used for calculations of the form \({\log _{10}}x\). For example, to work out that \(\log 10000 = 4\) ...

We give a necessary and sufficient condition for the Strassen functional law of the iterated logarithm for the Wiener process to hold when the topology is defined by a general class of norms on C(0, 1 ...

Now that you know what \({\log _a}x\) means, you should know and be able to use the following results, known as the laws of logarithms.
