EXPONENTIAL FORMULA RELATED TO THE GAUSS SEMIGROUP
Abstract: For the second derivative, an analogue of the classical Taylor’s formula is
considered on a suitable function space. The sum of the ”Taylor series” represents the Gauss
semigroup. This may be useful in describing the trajectories of some functions under the
action of the Gauss semigroup.
