Cristian Văideanu

Lect. dr. Cristian Văideanu is a Lecturer at the Department of Mathematics, Faculty of Mathematics of the Alexandru Ioan Cuza University of Iași (UAIC). His research focuses on set-valued analysis, formal concept analysis, and fuzzy set theory, with contributions to mathematical analysis and discrete mathematics. He has published works on measurable multifunctions, concept lattices, and web document analysis.

Research Interests include:

• Formal Concept Analysis and Lattice Theory
• Set-Valued Analysis and Multifunctions
• Fuzzy Set Theory and Similarity Relations
• Mathematical Analysis and Measure Theory

Recent Articles highlight his exploration of threshold conceptual structures in web documents, lower/upper concept lattices, and measurable multifunctions. These publications reflect his interdisciplinary approach spanning mathematics and computer science.

Teaching involves courses in formal languages, automata theory, and mathematical analysis. His educational materials include problem collections for calculus and sequences/series of functions.

Affiliations include the UAIC Mathematics Department, with ongoing contributions to academic conferences and collaborative research projects.
