Finding the extrema of functionals is similar to finding the maxima and minima of functions. Some of these maxima even correlate well with salinity extrema. He had previously wrestled in some shows of IGWA's predecessor, Lucha Libre Extrema Internacional. Isentropic fluids have two extrema (d"s"/d"T"=0) on the saturation vapour curve. Scale-space extrema detection produces too many keypoint candidates, some of which are unstable. Because of symmetry around the axis, there exist extrema with coordinates . The RS125 is revised and the Extrema suffix is dropped. Suppose a set of statistics such as average, extrema, location of extrema, standard deviation, etc. Finding strong extrema is more difficult than finding weak extrema. The first two options are collectively known as "local extrema". This statement is a direct consequence of how local extrema are defined. But at the stable and unstable extrema meet, and annihilate. Note that, in each case, the number of extrema is "N"+2, that is, 6. Unlike in the other kicks, the joints are moved into extrema. Together they are called the absolute extrema.
