The commentary of the scaling homes of the constitution capabilities w and vw of deep inelastic electron 1 2 nucleon scattering [1]+ has been taken by way of many folks as a sign for an approximate scale invariance of the realm. It was once mentioned via Wilson [2], that during many box theories it's attainable to assign a size d to each primary box, which proves to be a conserved quantum quantity so far as the main singular time period of an operator product enlargement at small distances ((x-y) +a) is con- JJ cerned++. Later it was once proven, on the canonical point, that during many box theories the size of a box appears to be like a c:pod quantum quantity even within the phrases much less singular at small (x-y) , so long as all of them belong to the most powerful \l mild cone singularity (i. e. (x-y)2+a) [3]. the belief that this sort of scale invariance at the mild cone be found in the operator product ex pansion of 2 electromagnetic currents has supplied us with a slightly typical rationalization of the saw scaling phenomena. we should always wish to point out, even if, that this ex planation can't account for the precocity with which scaling is being saw experimentally in strength areas, within which resonances nonetheless offer favourite contributions to the ultimate states [4].

Therefore the terms which would describe three- and more-particle decays can be included into the sum of the bound structures. +This means in the theory described here any kind of moreparticle-decays are also contained in principle. As in the theory discussed by Prof. Sandhas the problems with the asymptotic boundary conditions of the three- and moreparticle decay-channels appear also here. But very probably one can simplify these problems by putting the asymptotic boundary conditions already to a large part into the "ansatz" for the trial functions.

For V(R) and K(R,R') one obtains the following ex- plicit forms: (40) KT is the exchange term which comes from the kinetic energy operator and KV the exchange term which comes from the two-nucleon forces.

The same is true if one considers, for instance, two and more channel-problems and if one includes bound structures with linear variational amplitudes into the calculations.
