   <hidden TTP99-52  The criteria of irreducibility of multi--loop Feynman integrals >   The integration by parts recurrence relations allow to reduce some
 Feynman
 integrals to more simple ones (with some lines missing). Nevertheless the
 possibility of such reduction for the given particular integral was
 unclear.
 The recently proposed technique for studying the recurrence relations as
 by-product provides with simple criterion of the irreducibility.
