InverseSeries[s] takes the series s, and gives a series for the inverse of the function represented by s. InverseSeries[s, x] uses the variable x in the inverse series.
KCoreComponents[g, k] gives the k-core components of the underlying simple graph of g.KCoreComponents[g, k, "InDegree"] gives the k-core components with vertex in-degrees at ...
LineSpacing is an option for Style and Cell that specifies the spacing between successive lines of text.
Log2
(Built-in Mathematica Symbol) Log2[x] gives the base-2 logarithm of x.
LogBarnesG[z] gives the logarithm of the Barnes G-function logG(z).
MatrixQ
(Built-in Mathematica Symbol) MatrixQ[expr] gives True if expr is a list of lists or a two-dimensional SparseArray object that can represent a matrix, and gives False otherwise. MatrixQ[expr, test] gives ...
MemberQ
(Built-in Mathematica Symbol) MemberQ[list, form] returns True if an element of list matches form, and False otherwise. MemberQ[list, form, levelspec] tests all parts of list specified by levelspec.
MoebiusMu[n] gives the Möbius function \[Mu](n).
