• A variational inequality approach to constrained control problems 

  Neittaanmäki, Pekka; Tiba, D. (University of Jyväskylä, 1986)

• Parameter estimation for allometric trophic network models : A variational Bayesian inverse problem approach 

  Tirronen, Maria; Kuparinen, Anna (John Wiley & Sons, 2024)

  Differential equation models are powerful tools for predicting biological systems, capable of projecting far into the future and incorporating data recorded at arbitrary times. However, estimating these models' parameters ...

• Overlapping doman decomposition methods for the obstacle problem 

  Kuznetsov, Yuri A.; Neittaanmäki, Pekka; Tarvainen, Pasi (American Mathematical Society, 1994)

  In this paper overlapping domain decomposition methods are applied to the numerical solution of nonlinear grid variational problems arising from the approximation of the obstacle problem by the piecewise linear finite ...

• Biharmonic Obstacle Problem : Guaranteed and Computable Error Bounds for Approximate Solutions 

  Apushkinskaya, Darya E.; Repin, Sergey I. (Pleiades Publishing, 2020)

  The paper is concerned with an elliptic variational inequality associated with a free boundary obstacle problem for the biharmonic operator. We study the bounds of the difference between the exact solution (minimizer) of ...

• Thin obstacle problem : Estimates of the distance to the exact solution 

  Apushkinskaya, Darya E.; Repin, Sergey (European Mathematical Society Publishing House, 2018)

  We consider elliptic variational inequalities generated by obstacle type problems with thin obstacles. For this class of problems, we deduce estimates of the distance (measured in terms of the natural energy norm) between ...
