LogNormalDistribution[\[Mu], \[Sigma]] represents a lognormal distribution derived from a normal distribution with mean \[Mu] and standard deviation \[Sigma].
LogPlot
(Built-in Mathematica Symbol) LogPlot[f, {x, x_min, x_max}] generates a log plot of f as a function of x from x_min to x_max. LogPlot[{f_1, f_2, ...}, {x, x_min, x_max}] generates log plots of several ...
LogSeriesDistribution[\[Theta]] represents a logarithmic series distribution with parameter \[Theta].
LongestCommonSequence[s_1, s_2] finds the longest sequence of contiguous or disjoint elements common to the strings or lists s_1 and s_2.
LongestCommonSubsequence[s_1, s_2] finds the longest contiguous subsequence of elements common to the strings or lists s_1 and s_2.
Longest
(Built-in Mathematica Symbol) Longest[p] is a pattern object that matches the longest sequence consistent with the pattern p.
Longitude[pos] gives the longitude in degrees of a geographic position specified by pos.Longitude[pos, datum] gives the longitude referring to the specified geodetic datum.
