Dimitar Petkov Tsvetkov

Dimitar Petkov Tsvetkov is a Professor at the Department of Mathematical Analysis and Applications, Faculty of Mathematics and Informatics, St. Cyril and St. Methodius University of Veliko Turnovo. His research spans differential equations, applied statistics, neural networks, psychometrics, and stochastic processes, with applications in psychology, ecology, and education.

Research interests focus on:

• Probability and stochastic modeling (Markov chains, queueing theory)
• Psychometric theory and test validation (Item Response Theory, population homogeneity)
• Mathematical biology (predator-prey systems, population dynamics)
• Educational mathematics (competitions, pedagogical strategies)
• Applied computational methods (neural networks, Monte Carlo algorithms)

Publications (2015–2024) emphasize probability, statistics, and applied mathematics, with recurring themes in Markov processes, educational assessment, ecological modeling, and mathematics pedagogy. Recent works show increased focus on theoretical probability and statistical applications in social sciences.

Grants include participation in the project Maximizing the comparative achievements of the border regions (2010–2012), analyzing regional governance, labor markets, and EU integration effects in Bulgarian-Romanian border areas.
