Abstract
We consider the behavior of distances between vertices and number of subtrees, as topological indices, in trees. The extremal ratios of the corresponding local functions of such indices at the "middle part" or leaves are given and the structures achieving such extremal ratios are characterized. This is joint work with Laszlo Szekely.
