and has authored several books on the topic of integration, and numerous papers on these topics and others related to many areas of
real analysis and
measure theory
In mathematics, the concept of a measure is a generalization and formalization of geometrical measures ( length, area, volume) and other common notions, such as mass and probability of events. These seemingly distinct concepts have many simil ...
. Pfeffer gave his name to the
Pfeffer integral, which extends a
Riemann-type construction for the integral of a measurable function both to higher-dimensional domains and, in the case of one dimension, to a superset of the
Lebesgue integrable functions.
