The derivatives of the Bott class and those of the Godbillon–Vey class with respect to infinitesimal deformations of foliations, called infinitesimal derivatives, are known to be represented by a formula in the projective Schwarzian derivatives of holonomies , . It is recently shown that these infinitesimal derivatives are represented by means of coefficients of transverse Thomas–Whitehead projective connections . We will show that the formula can be also deduced from the latter representation.
