In this work we consider the comparison of planar and planar parquet approximations for zero-dimensional hermitian matrix models. We discuss how the parquet approach reproduces planar one for matrix model ϕ4, multi-trace model, two-matrix model and

We observe some suitable examples of Calabi-Yau threefolds for heterotic superstring compactifications. It is reasonable to seek CY threefolds with Euler characteristic equals ±6 because of generation’s number. Hosotani mechanism for violations of

LCFT is special conformal field theory with logarithmic terms in operator product expansion OPE. It is well-known that it is possible to construct operators with logarithmical terms in OPE at Liouville model. Here we discuss this topic for some gener

This paper examines the comparison of planar and planar parquet approximation in the zero-dimensional hermitian matrix models. We discuss how the parquet approximation reproduces the results of a planar approach to matrix model φ4, multitrace model,

We consider the Goldstone Hermitian matrix model with a multitrace term. When defining the solution on two intervals, we introduce a special parameter ξ describing the phase. We discuss the phase existence conditions at ξ = 0 (or 1) and at ξ = 1/2

The planar parquet approximation is examined for the simplest two-trace matrix model. The propagator, four-point vertex, and values of critical coupling constants obtained with the help of the parquet equations and solution of the planar equation are
