Applying multiquadric quasi-interpolation to solve Fokker-Planck equation
(Işık University Press, 2023-01)The Fokker-Planck equation (FPE) arises in various fields in physics, chemistry, natural science. It is difficult to obtain analytical solutions, accordingly we resort to numerical methods. In this study, we present a ... -
Regularized trace on separable Banach spaces
(Işık University Press, 2023-01)If H is a separable Hilbert space, Gül (2008) has shown that a regularized trace formula can be computed on L² (H, [0, ?]) for a second order differential operator with bounded operator-valued coefficients, where H is a ... -
Contraction and domination in fuzzy graphs
