This 1918 publication is a rare and significant author's edition of a mathematical work by the prominent Georgian scientist Georgy (Giorgi) Nikolaevich Nikoladze (1888–1931). The book presents the author's theoretical work on the foundations of a "Trans-Cartesian" analytic geometry, representing an original contribution to the field. Published in Tiflis (present-day Tbilisi) by the author himself during the tumultuous year following the Russian Revolution and Georgian independence, this 46-page softcover volume is a true bibliographic rarity. Its status as an "author's edition" (издание автора) and its publication in the South Caucasus at that historical moment make it a unique artifact of scientific and publishing history. This work underscores the high level of the Georgian mathematical school in the early 20th century and is a valuable collectible for historians of mathematics, specialists in the history of Georgian science, and bibliophiles.
