Aims and organization of the Division
Activities of the Division include:
- gathering staff members that work in similar, same or compatible scientific areas based on Mathematical Analysis
- professional, technological and innovation activities

Division for Mathematical Analysis was formed in 2009. It gathers staff members whose scientific activities and interests are related to the following fields of Mathematics:
Functional Analysis
Numerical Analysis and Applications
Dynamical Systems

Differential Geometry
Division consists of six members, five of which hold a PhD degree while one member holds a master’s degree. Five members hold a tenure track position, while one holds position of a lecturer.

Teaching
Members of the Division participate in teaching of courses on both undergraduate and graduate study programme in Mathematics and they run courses on Department of Physics, Department of Informatics, Department of Biotechnology and on Faculties of Humanities and Social Sciences, Civil Engineering and Engineering.
For their courses, most staff members have formed corresponding e-courses on systems Mudri and Merlin, thus implementing the most advanced didactic accomplishments in the educational process. Furthermore, due to the specificity of courses thought by the members of the Division (like Numerical Mathematics or Mathematical Statistics), we regularly follow trends in the IT technology so that the students can work in recent and widely accepted software packages and programming languages (like Phyton, C++ or R).
Through their teaching activities, members of the Division support professional activities of students which resulted with a series of papers produced in a collaboration between staff members and their students. Some of the most recent ones are:
• D. Čudina, I. Slamić: Some applications of the properties of convexity and concavity in economics, Croatian mathematical electronic journal math.e 31 (2017).
• D. Krizmanić, V. Skobljanec: Some dilemmas, paradoxes and delusions in probability, Mathematics and School 18 (2017), 123-127.
Professional activities
Besides activities related to research and teaching, members of the Division are involved in professional activities in the areas of Mathematics, Applied Mathematics and Engineering, Mathematics Education and popularization of science. In a collaboration with the Agency for upbringing and education, in 2015 and 2018 the Division has organized Rijeka mathematical meetings with the purpose of professional development of elementary and high school teachers and popularization of Mathematics among high school students.
