The interaction among the spectral thought of Schr|dinger operators and probabilistic issues kinds the most subject of those notes, written for the non-specialist reader and meant to supply a short and elementaryintroduction to this box. An try is made to teach uncomplicated rules in statu nascendi and to keep on with their overview from basic beginnings via to extra complicated effects. The time period "genetic" within the name refers to this proceedure. the writer concentrates on 2 issues which, within the heritage of the topic, were of significant conceptual significance - at the one hand the Laplacian is a random medium and the left finish of its spectrum (leading to massive deviation difficulties for Brownian movement and the hyperlink to thenotion of entropy) and at the different, Schr|dinger operators with common ergodic potentials in one-dimensional area. rules and ideas are defined within the least difficult, attainable environment and via a number of attribute issues of heuristic arguments previous rigorous proofs.
