• Finite element approximation for a div-rot system with mixed boundary conditions in non-smooth plane domains 

  Křížek, Michal; Neittaanmäki, Pekka (Československá akademie věd. Matematický ústav., 1984)

  The authors examine a finite element method for the numerical approximation of the solution to a div-rot system with mixed boundary conditions in bounded plane domains with piecewise smooth boundary. The solvability of the ...

• Internal FE approximation of spaces of divergence‐free functions in three‐dimensional domains 

  Křižek, Michal; Neittaanmäki, Pekka (Wiley, 1986)

  The space of divergence‐free vector functions with vanishing normal flux on the boundary is approximated by subspaces of finite elements having the same property. An easy way of generating basis functions in these subspaces ...

• Existence of homoclinic orbits and heteroclinic cycle in a class of three-dimensional piecewise linear systems with three switching manifolds 

  Zhu, Bin; Wei, Zhouchao; Escalante-González, R.J.; Kuznetsov, Nikolay V. (American Institute of Physics, 2020)

  In this article, we construct a kind of three-dimensional piecewise linear (PWL) system with three switching manifolds and obtain four theorems with regard to the existence of a homoclinic orbit and a heteroclinic cycle ...

• Intregrating metallic wiring with three-dimensional polystyrene colloidal crystals using electron-beam lithography and three-dimensional laser lithography 

  Tian, Yaolan; Isotalo, Tero; Konttinen, Mikko P.; Li, Jiawei; Heiskanen, Samuli; Geng, Zhuoran; Maasilta, Ilari (IOP Publishing, 2017)

  We demonstrate a method to fabricate narrow, down to a few micron wide metallic leads on top of a three-dimensional colloidal crystal self-assembled from polystyrene (PS) nanospheres of diameter 260 nm, using electron-beam ...

• L2-variation of Lévy driven BSDEs with non-smooth terminal conditions 

  Geiss, Christel; Steinicke, Alexander (International Statistical Institute; Bernoulli Society for Mathematical Statistics and Probability, 2016)

  We consider the L2-regularity of solutions to backward stochastic differential equations (BSDEs) with Lipschitz generators driven by a Brownian motion and a Poisson random measure associated with a Lévy process (Xt)t∈[0,T]. ...
