Being hosted by, thus using the content management system, this blog has posts, pages, and media. This directory is for the pages and the verbal media (namely pdf files).

The posts, such as this one, have initial publication dates and can be seen at, in reverse chronological order. I have them listed in forward order 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, which will then show at the bottom which 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 pages, although search engines find some of them. Much less do I know how one would find media, although the media allowed by WordPress now include pdf files. I have uploaded a number of these, and created a number of pages. and in this post (which I hope to remember to keep up to date), I try to classify them, if only to remind myself what they are.

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.



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”:



Pages describing (as well as listing) categories of posts


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.

  • Aksiyomatik Kümeler Kuramı Özeti (“summary of axiomatic set theory”: an attempt in fall 2019 to supply just that in html; 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)

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