· PicardFuchs equations:
X x be a family of n-dimensional algebraic varieties,
with smooth fibres over the complement of a finite set.
Choose a holomorphic n-form on a smooth fibre V0 V, and
n-cycles 1, . . . , r that give a basis for its nth homology.
Then can be extended to a meromorphic family of n-forms (x),
and the cycles (homology classes) to (multivalued!) functions of x.
The periods i(x)
(x) are multivalued too, but satisfy a Fuchsian
