  • Dirichlet problem for Poisson equations in Jordan domains 
    Gutlyanskii, V.; Ryazanov, V.; Yakubov, E. (Праці Інституту прикладної математики і механіки НАН України, 2018)
    We study the Dirichlet problem for the Poisson equations △u(z) = g(z) with g ∈ Lp, p > 1, and continuous boundary data φ : ∂D → ℝ in arbitrary Jordan domains D in ℂ and prove the existence of continuous solutions u of the problem.
  • On convergence theory for Beltrami equations 
    Ryazanov, V.; Srebro, U.; Yakubov, E. (2008)
    This paper is devoted to convergence theorems which play an important role in our scheme for deriving theorems on the existence of solutions of the Beltrami equations.
  • On integral conditions in the mapping theory 
    Ryazanov, V.; Srebro, U.; Yakubov, E. (Український математичний вісник, 2010)
    It is established interconnections between various integral conditions that play an important role in the theory of space mappings and in the theory of degenerate Beltrami equations in the plane.
  • On recent advances in the Beltrami equations 
    Gutlyanskii, V.; Ryazanov, V.; Srebro, U.; Yakubov, E. (Український математичний вісник, 2010)
    We give an exposition of the recent progress in the theory of the Beltrami equations with the degeneration.
  • On theory of multivalent solutions for Riemann Hilbert problem 
    Ryazanov, V. (Труды Института прикладной математики и механики, 2015)
    It is proved the existence of multivalent solutions for the Riemann–Hilbert problem in the general settings of finitely connected domains bounded by mutually disjoint Jordan curves, measurable coefficients and measurable ...
  • The Beltrami equation and ring homeomorphisms 
    Ryazanov, V.; Srebro, U.; Yakubov, E. (Український математичний вісник, 2007)
    With the aid of results by Gehring, we introduce and study plane ring Q-homeomorphisms. This study is then applied in deriving general principles on the existence and uniqueness of homeomorphic ACL solutions to the Beltrami ...
  • Uniqueness and topological properties of number representation 
    Dovgoshey, O.; Martio, O.; Ryazanov, V.; Vuorinen, M. (Український математичний вісник, 2004)
    Let b be a complex number with |b| > 1 and let D be a finite subset of the complex plane C such that 0 ∊ D and card D ≥ 2. A number z is representable by the system (D, b) if z = Σajbj , where aj ∊ D. We denote by F the ...
