Parvanov’s work primarily investigates the theoretical foundations of best approximation using operators like Bernstein-type, Baskakov-type, and Meyer-König-Zeller-type. His studies emphasize error estimation, K-functionals, and moduli of smoothness to characterize approximation rates.

His publications (1994–2011) demonstrate expertise in:

• Weighted approximation techniques
• Trigonometric and spline approximations
• Operator theory in numerical analysis
• Exact constants in quadrature formulae
• Moduli of smoothness in multivariate approximation
• Polynomial and functional inequalities
