WebExamples of discontinuous linear maps are easy to construct in spaces that are not complete; on any Cauchy sequence of linearly independent vectors which does not have a limit, there is a linear operator such that the quantities grow without bound. In a sense, the linear operators are not continuous because the space has "holes". WebThe function has a discontinuity of the first kind at if There exist left-hand limit and right-hand limit ; These one-sided limits are finite. Further there may be the following two options: The right-hand limit and the left-hand limit are equal to each other: Such a point is called a removable discontinuity . early years educator book penny tassoni https://jpasca.com
