In functional analysis, double operator integrals (DOI) are integrals of the form where T : G → H is a bounded linear operator between two separable Hilbert spaces, are two spectral measures, where P stands for the set of orthogonal projections over H , and φ is a scalar-valued measurable function called the symbol of the DOI. The integrals are to be understood in the form of Stieltjes integrals. Double operator integrals can be used to estimate the differences of two operators and have applicat
