• Optimization of the domain in elliptic variational inequalities 

  Neittaanmäki, Pekka; Sokolowski, J.; Zolesio, J. P. (University of Jyväskylä, 1986)

• Accessible parts of boundary for simply connected domains 

  Koskela, Pekka; Nandi, Debanjan; Nicolau, Artur (American Mathematical Society, 2018)

  For a bounded simply connected domain Ω ⊂ R2, any point z ∈ Ω and any 0 < α < 1, we give a lower bound for the α-dimensional Hausdorff content of the set of points in the boundary of Ω which can be joined to z by a John ...

• Quantitative lower bounds to the Euclidean and the Gaussian Cheeger constants 

  Julin, Vesa; Saracco, Giorgio (Suomen matemaattinen yhdistys ry, 2021)

  We provide a quantitative lower bound to the Cheeger constant of a set Ω in both the Euclidean and the Gaussian settings in terms of suitable asymmetry indexes. We provide examples which show that these quantitative estimates ...

• 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 ...

• Sobolevin epäyhtälön parhaasta vakiosta 

  Helén, Markus (2012)
