According to Suceavă, "Barbilian's metrization procedure is important for at least three reasons: (1) It yields a natural generalization of Poincaré and Beltrami–Klein's hyperbolic geometries; (2) It has been studied in the context of the study of Apollonian metric; (3) Provides a large class of examples of Lagrange generalized metrics irreducible to Riemann, Finsler, or Lagrange metrics."

Suceavă attributes these moves to be opportunistic devices in a professional advancement plan and ignores Barbu’s own explanation, that he was attempting to deflect attention from the fact that he was hiding in his house his wife’s brother, a German citizen who eluded conscription by staying hidden in Romania.

A systematic study of projective planes over large classes of associative rings was initiated by D. Barbilian. His very general approach in remained rather unsatisfactory, however, his axioms were partly of a geometric nature, partly algebraic as pertaining to the ring of coordinates, and there were

He answered in 1959 with an article which described "a very general procedure of metrization through which the positive functions of two points, on certain sets, can be refined to a distance." Besides
Blumenthal and Kelly, articles on "Barbilian spaces" have appeared in the 1990s from Patricia Souza,

According to
Loveday Kempthorne and Peter Donelan, Barbu "saw mathematics and poetry as equally capable of holding the answer to understanding and reaching a transcendental ideal." He is known as "one of the greatest Romanian poets of the twentieth century and perhaps the greatest of all" according

were introduced by Werner
Leissner in 1975, in two papers ("Affine Barbilian planes I and II"). Referring to these papers, Dirk Keppens says that Leissner introduced this terminology "as a tribute to Barbilian, who was one of the founders of (projective) ring geometry."

As a mathematician, Barbilian authored 80 research papers and studies. His last paper, written in collaboration with
Nicolae Radu, appeared posthumously, in 1962, and is the last in the cycle of four works where he investigates the Apollonian metric.
