Abstract: Let w: Map(X,Y;f) -> Y denote a general evaluation
fibration. Working in the setting of rational homotopy theory via
differential graded Lie algebras, we identify the long exact
sequence induced on rational homotopy groups by w in terms of
(generalized) derivation spaces and adjoint maps. As a
consequence, we obtain a unified description of the rational
homotopy theory of function spaces, at the level of rational
homotopy groups, in terms of derivations of Quillen models and
adjoints. In particular, as a natural extension of a result of
Tanre, we identify the rationalization of the evaluation subgroups
of a map f: X -> Y in this setting. As applications, we consider
a generalization of a question of Gottlieb, within the context of
rational homotopy theory. We also identify the rationalization of
the G-sequence of f and make explicit computations of the homology
of this sequence. In a separate result of independent interest,
we give an explicit Quillen minimal model of a product AxX, in the
case in which A is a rational co-H-space.
