Jordi Guàrdia is an associate professor in the Math Department at Universitat Politècnica de Catalunya-Barcelona Tech. His research has been focused in arithmetic geometry and computational number theory. Jointly with J. Montes and E. Nart, he has been involved in the development of Montes algorithm and its theoretical and computational applications, including the Magma package ”+Ideals”. They are now working in higher rank valuation theory and the interaction between number theory and singularities theory. He is one of the founders of the biannual conference” Jornadas de Teoria de Numeros”, and is an active member of the ”Seminaride Teoria de Nombres de Barcelona”.

Diana Savin is an associate professor at the Faculty of Mathematics and Computer Science, Transilvania University of Bra?ov, Romania. Diana Savin graduated from the Faculty of Mathematics and Computer Science of the University of Bucharest in 1996. She obtained the PhD degree in Mathematics at Ovidius University of Constanta, Romania, in 2004, with a thesis about Diophantine equations. Diana Savin works in number theory. Her research directions are algebraic number theory (especially ramification theory in algebraic number fields), associative algebras, computational numbertheory and combinatorics. She wrote several research articles on these areas. Alone or jointly with V. Acciaro, M. Taous and A. Zekhnini, she has been studying quaternion algebras over some algebraic number fields, using ramification theory in algebraic number fields.
Montserrat Vela is an associate professor of the Math Department at Universitat Politècnica de Catalunya-Barcelona Tech. She has worked mainly in the inverse problem in Galois theory, Nowadays, her research is focused on Hopf-Galois theory, having published some relevant papers jointly with T. Crespo and A. Rio. She is an active member of the ”Seminari de Teoria de Nombres de Barcelona”.
Abdelkader Zekhnini is an associate professor at the Mohammed Premier University, Sciences Faculty, Department of Mathematics, Oujda, Morocco. He obtained the PhD degree in Mathematics in 2014, at the same university with a thesis on capitulation theory and Hilbert class field towers. Before, he was a mathematics teacher in high schools. Abdelkader Zekhnini works in many directions of number theory as algebraic number theory (especialy capitulation theory), Hilbert class field towers, Iwasawa theory, commutative algebra (Integer valued polynomials, Polya fields) and associative algebras. He wrote several research papers on these areas, over 40, published in Web of Science indexed journals.
