The number of local maxima (resp., local minima) in a tree T∈𝒯n rooted at r∈[n] is denoted by Mr(T) (resp., by mr(T)). We find exact formulas as rational functions of n for the expectation and
variance of M1(T) and mn(T) when T∈𝒯n is chosen
randomly according to a uniform distribution. As a consequence,
a.a.s. M1(T) and mn(T) belong to a relatively small interval
when T∈𝒯n.
