Interests

I enjoy researching group C*-algebras and related topics.
I also enjoy all you can eat sushi, Photoshopping, and anything computer-related.

Papers

Authors Title Journal Link Notes
Shirly Geffen, Dan Ursu Simplicity of crossed products by FC-hypercentral groups Preprint (arXiv), 2023 arXiv:2304.07852
Matthew Kennedy, Se-Jin Kim, Xin Li, Sven Raum, Dan Ursu The ideal intersection property for essential groupoid C*-algebras Preprint (arXiv), 2021 arXiv:2107.03980
Tattwamasi Amrutam, Dan Ursu A generalized Powers averaging property for commutative crossed products Transactions of the American Mathematical Society 375 (2022), no. 3, 2237-2254 Journal (DOI) | arXiv arXiv version is the accepted manuscript. See [1]. Also, this can be dedicated to the public domain 28 years after publication. Remind me.
Dan Ursu Characterizing traces on crossed products of noncommutative C*-algebras Advances in Mathematics 391 (2021), 107955 Journal (DOI) | arXiv arXiv version is the accepted manuscript. See [1]
Dan Ursu Relative C*-simplicity and characterizations for normal subgroups Journal of Operator Theory 87 (2022), no. 2, 471-486 Journal (DOI) | arXiv arXiv version is the accepted manuscript. See [1].

[1] The accepted manuscript of a paper is the version that includes all corrections made during the peer-review process. Unless noted otherwise, the only additional corrections in the journal version are some minor grammatical mistakes, small typos in the references (sorry Frolík!), and updating references from arXiv to published.
