    Source documentation

    A power singularity has at most twice the endpoint mass on an interval of length b-a. This is the root-independent estimate in the large-slope case of ker:scalar-interval.

    If the slope is small, the affine function stays a fixed distance from zero.

    The scalar interval estimate ker:scalar-interval, with an explicit constant. The singular case A=0 is understood in the extended sense in the manuscript; the finite estimate needed off the exceptional line is stated here.
