Tiberiu Popoviciu Institute of Numerical Analysis
The institute is organizing in November 2024 the international conference Numerical Analysis, Numerical Modeling, Approximation Theory (NA-NM-AT 2024) as part of the 2024 edition of the Cluj Academic Days.
The conversion of the LaTeX files into HTML (with their posting on the website) has been started for the scientific papers published in the last 10 years (see, e.g., paper1, paper2, paper3, paper4, paper5, paper6, etc.).
This operation is required in order to improve the interaction of our website with the search engine, as this standard is de facto for certain publishing houses (e.g., Springer, Elsevier, etc.).
This process has been finalized for the papers published since 2010 in the journal edited at ICTP, J. Numer. Anal. Approx. Theory.
The institute has started recovering and posting its Annual Reports, since its foundation, in 1951.
The list of papers are completed for the years 1951-1956, 1957-1975 (in progress), 1976-1989 (March 7, 2024), while the full activity reports of 1990-present were already posted for some years.
Here we see the first page of the Annual Report of 1957, when the Institute started to build electronic computers (see the history page).
The institute has organized in November 2023 the international conference Numerical Analysis, Numerical Modeling, Approximation Theory (NA-NM-AT 2023) as part of the 2023 edition of the Cluj Academic Days.
The institute has organized the (online) conference Numerical Analysis, Numerical Modeling, Approximation Theory (NA-NM-AT 2022) during October 26-28, as part of the 2022 edition of the Cluj Academic Days.
In 2022 Journal of Numerical Analysis and Approximation Theory – edited by the Institute – has celebrated 50 years.
Dr. Emil Cătinaș, Editor-in-Chief, has given the talk “The 50th anniversary of the Journal of Numerical Analysis and Approximation Theory“, at the opening ceremony of the Cluj Academic Days 2022 (October 7).
On October 12, 2023, the editorial board is organizing a workshop with the members of the Editorial Board and with the members of ICTP who are supporting the JNAAT activities in order to discuss further management strategies.
In 2021 the Institute has celebrated 70 years from its foundation.
The symposium 70 years from the foundation of the „Tiberiu Popoviciu” Institute of Numerical Analysis was organized on October 28, 2021, in the frame of Academic Days of Cluj-Napoca 2021.

acad. Tiberiu Popoviciu
One of the greatest Romanian mathematicians.
One of the Romanian computer pioneers.
Appears in the select History of Approximation Theory.
Some of the first electronic computers in Romania built here:
- MARICA, ’59, relay computer;
- DACICC-1, ’63, 3rd in Romania, but 1st with transistors & RAM memory;
- DACICC-200, ’68, most powerful Romanian computer; 1st with OS & compiler.
The tree of the PhD descendants of T. Popoviciu, G. Călugăreanu and D.V. Ionescu.
The first ionic implantation device from Romania
In the seventies was constructed a ionic implantation device, based on electrostatic field.
It was subsequently improved at ITC, in 1976 (for electromagnetic field).
