3 Swelling and partition function of an isolated chain at the tricritical point 

The functions °T0(y) aRd °Ti(y) can be considered as renormalization factors and effective exponents can be associated with them we define the exponents by the following formulae which are analogous to (1Z3.66) 

The expansions of these exponents with respect to y are obtained from (14.6.38) 

These effective exponents can be re-expressed in terms parameter h. Let us set of the tricritical
