,Local Time and Tanaka’s Formula,In this chapter . denotes a Brownian motion in ℝ. For each . ∞ ℝ we shall obtain a decomposition, known as Tanaka’s formula, of the positive submartingale |. — .| as the sum of another Brownian motion . and a continuous increasing process .(·, .). The latter is called the local time of . at ., a fundamental notion invented by P. Lévy (see ).
