Creșterea radială a arborilor variază de la un sezon de vegetație la altul, datorită variației factorilor de mediu de la un an la altul. Poluarea aerului poate modifica comportamentul normal al creșterii arborilor atât în ceea ce privește d

We compute uniform rates of metastability for the Ishikawa iteration of a Lipschitz pseudo-contractive self-mapping of a compact convex subset of a Hilbert space. This extraction is an instance of the proof mining program that aims to apply tools fro
