On the critical behaviour of hermitean f-matrix models in the double scaling limit with f >= 3
S. Balaska, J. Maeder, W. Ruehl
An algorithm for the isolation of any singularity of f-matrix models in the double scaling limit is presented. In particular it is proved by construction that only those universali…
The Continuous Series of Critical Points of the Two-Matrix Model at N -> infinity in the Double Scaling Limit
S. Balaska, J. Maeder, W. Ruehl
The critical points of the continuous series are characterized by two complex numbers l_1,l_2 (Re(l_1,l_2)< 0), and a natural number n (n>=3) which enters the string susceptibility…
Perturbative approach to the critical behaviour of two-matrix models in the limit N -> infinity
S. Balaska, J. Maeder, W. Ruehl
We construct representations of the Heisenberg algebra by pushing the perturbation expansion to high orders. If the multiplication operators tend to differential operator…
Greensite-Halpern stabilization of singularities in the limit
J. Maeder, W. Ruehl
The Greensite-Halpern method of stabilizing bottomless Euclidean actions is applied to zerodimensional O(N) sigma models with unstable singularities in the limit…
Sigma models with singularities in Euclidean spacetime of dimension 0<=D<4 and in the limit N->infinity
J. Maeder, W. Ruehl
For the case of the single-O()-vector linear sigma models the critical behaviour following from any singularity in the action is worked out in the double scaling limit $N…
Double Scaling Limits, Airy Functions and Multicritical Behaviour in O(N) Vektor Sigma Models
J. Maeder, W. Ruehl
O(N) vector sigma models possessing catastrophes in their action are studied. Coupling the limit N --> infinity with an appropriate scaling behaviour of the coupling constants, the…
