Directory

This directory has the following sections.

The links in the sections are sometimes to posts of this blog, but mostly to pages and media (especially pdf files).

Posts, pages, and media are what this blog has, because it uses the WordPress.org content management system, by virtue of being hosted by WordPress.com. You are now reading a post, as you can tell from its having an initial publication date both in its address and somewhere at the end of its body. The contents of any post can always be edited. I shall be editing this post in order to make available, or highlight, pages, verbal media (namely pdf files) and some series and categories of posts.

In principle, all of my posts can be seen at polytropy.com, in reverse chronological order. I have them listed in forward order, by year, on my About page. As I explain there, I try to keep track of posts with tags and categories. Moreover, if one post revisits a theme of another post, I try to link to that post. Every post shows (at the bottom) which other posts are linked to it.

A dream, never to be realized, would be to have all of my ideas as well-organized as in Wittgenstein’s Tractatus Logico-Philosophicus.

I don’t know how the random visitor can find my pages, although search engines find at least some of them. Much less do I know how one would find my media, although the media allowed by WordPress now include pdf files. I have uploaded a number of these, and created a number of pages.

It would be possible to have all top-level pages included automatically in the menu which now forms a horizontal list at the top of each post and page.

The directory proper now begins.

Prose

Poetry

Poetry, in the broad etymological sense of something made; call it conceptual art, or whatever you like, but it’s all referred to in the post “Discrete Logarithms”:

Mathematics

Categories

Pages describing (as well as listing) categories of posts

Series

There are series of posts about particular works of prose and poetry. I could make each one into a category, but so far I have not. One post in the series may serve as an index, or else a page may serve.

Courses

For my courses I normally prepare pages on my department’s server; but since I cannot access this from home, I may also use the blog.

  • Kümeler Kuramı (“Set theory,” including my attempts to summarize in html the contents of a course in axiomatic set theory for which I have also written a full text in LaTeX. For the summary of fall 2019, I had not yet discovered the usefulness of pandoc as described in “LaTeX to HTML”)

  • Analitik Geometri Özeti (“summary of analytic geometry,” for a course in spring 2020; as the Covid-19 lockdown took hold, the page just became the course page)

  • Ordinal Analiz (“ordinal analysis,” that is, set theory with emphasis on the ordinals as a structure analogous to the linearly ordered set of real numbers studied in so-called real analysis; the post “Ordinals” also takes up the analogy; I made the page for a course in Şirince, in case I wanted to change the page while I was there, though in the event I didn’t; notes from the second week, in English, are on a departmental page, along with the syllabus for a summer course in 2020 that was cancelled)

  • Öklid (Resources for the course Öklid geometrisine giriş, “introduction to Euclidean geometry,” fall 2020)

  • Topoloji (homepage for a graduate topology course, fall 2020, with links to weekly notes in English. The notes are mostly in pdf format, for A6 paper in landscape orientation; but one week I used html)

  • Ayşe Berkman’ın yedek sayfasıdır (for her spring 2020 course during the lockdown)

Writing of others
