This PhD thesis deals with the following statistical problems: Variable selection in high-Dimensional Linear Regression, Clustering in the Gaussian Mixture Model, Some effects of adaptivity under sparsity and Simulation of Gaussian processes.Under the sparsity assumption, variable selection corresponds to recovering the "small" set of significant variables. We study non-asymptotic properties of this problem in the high-dimensional linear regression. Moreover, we recover optimal necessary and sufficient conditions for variable selection in this model. We also study some effects of adaptation under sparsity. Namely, in the sparse vector model, we investigate, the changes in the estimation rates of some of the model parameters when the noise l...
