In the context of the physical and mathematical theory of percolation, a percolation transition is characterized by a set of universal critical exponents, which describe the fractal properties of the percolating medium at large scales and sufficiently close to the transition.
Exponents and space dimension the critical-point exponents depend on the dimensionality \(d\\) the theory was found to be illuminated by treating \(d\) as continuously variable and of any magnitude. There is a class of critical-point exponent relations, often referred to as hyperscaling, in which \(d\) appears explicitly.

We propose a generalization of the coherent anomaly method to extract the critical exponents of a phase transition occurring in the steady-state of an open quantum many-body system. \\bf 55, 4205 (1986)] for equilibrium systems, is based on the scaling properties of the singularity in the response functions determined through.
The exponents are universal in the sense that they only depend on the type of percolation model and on the space dimension. They are expected to not depend on microscopic details such as the lattice structure, or whether site or bond percolation is considered. This article deals with the critical exponents of random percolation.
The analysis of the series yields accurate estimates of both the critical point and critical exponent, and shows that a recent conjecture for the exact value of the semi-meander critical exponent is unlikely to be correct, while the conjectured exponent value for closed and open meanders is not inconsistent with the results from the analysis.

Critical exponents are the most studied quantities in the theory of phase transitions, because they characterize universality classes and are easier to calculate. They have been extensively used to test rg predictions by comparing them with other results (experiments, high- or low-temperature series expansion, monte-carlo simulations).
For example, to construct a 95% confidence interval assuming a normal distribution, we would need to determine the critical values that correspond to 5% level.
The critical exponents depend on the range of field and temperature studied for their determination, either because of the existence of regular terms, or because of the existence of crossovers between different types.
