nLab Alexander Rosenberg


There are at least two Alexander Rosenbergs (and one Jonathan Rosenberg) in mathematics:

Alexander L. Rosenberg

Sasha Rosenberg had defended in 1973 dissertation at Moscow State University studying Tannakian reconstruction theorems, mainly using methods of functional analysis. His main goals were in representation theory. Until leaving Soviet Union around 1987, Rosenberg worked in applied mathematics; on the side however he was developing some methods in representation theory which included functional analysis and categorical and ring/module theoretic methods, and the noncommutative localization in particular. A main construction, presented at a conference at Baikal (1981), was a new spectrum of a ring, so-called left spectrum, later generalized to a spectrum of an abelian category, used to prove (in the quasicompact case) the Gabriel-Rosenberg reconstruction theorem for commutative schemes; more spectral constructions followed. This work outgrown into a wide ongoing work on foundations of noncommutative algebraic geometry, including a natural definition of noncommutative scheme. More recently he proposed a new framework for nonabelian derived functors, including a new version of algebraic K-theory. Other related entries in nnLab include Q-category, neighborhood of a topologizing subcategory, sheaf on a noncommutative space, spectral cookbook.

Rosenberg’s coauthors in pure mathematics works are Valery Lunts and Maxim Kontsevich. One should be warned that most of the newly released articles of Rosenberg are not at the arXiv but at the Max Planck Bonn preprint server and many of works are republished in a volume

Rosenberg’s available papers and online resources include:
