The aim of this study is to analyse past and future sustainability of total public debt in Turkey. The analysis is based on econometric studies and simulations. The data are taken quarterly in order to take into account intra annual effects important in Turkey, given the strong volatility of the...

We propose identifying the drift and the diffusion functions of an ergodic scalar stochastic differential equation using repeated eigenfunction estimation. The transition density will be estimated in a new way involving Kolmogorov’s backward equation, neural networks and functions of our...

We propose to estimate the eigenfunctions of the infinitesimal generator of a stochastic differential equation as the solutions of an integral equation.

We propose a simple cognitive model where qualitative and quantitative comparisons enable animals to identify objects, associate them with their properties held in memory and make naive inference. Simple notions like equivalence relations, order relations are used. We then show that such...
