Dear colleagues,

We are in the process of preparing my book, Embarking on Adventurous Journeys Through Some Subjects in Pure Mathematics, for submission to arXiv in the mathematics category and are currently seeking an endorser. As you may be aware, arXiv mandates that new authors obtain endorsement from a registered contributor within the relevant field.
