Surrounding auxin maxima are cells with low auxin troughs, or auxin minima. Finding the extrema of functionals is similar to finding the maxima and minima of functions. Hence, diffraction patterns usually have a series of maxima and minima. Finding global maxima and minima is the goal of mathematical optimization. They do not in any way imply that maxima/minima in general are normals. They are helpful in finding maxima and minima in the wind pattern. Wavelength is determined by measuring the distance between two adjacent minima. Following the deep minima, smaller brightness peaks are observed. Most of the diffracted light falls between the first minima. Solar minima is correlated with changes in climate. The maximum eccentricity between those two minima is 0.12. The locations of all the minima can be found analytically. Not all multiple minima have equal values of the objective function. One, servoing to a local minima and second, reaching a Jacobian singularity. Others are anharmonic, such as sidechains that jump between separate discrete energy minima, or rotamers.
