摘要
Some method is proposed for finding Ein components in moduli spaces of stable rank 2 vector bundles with first Chern class c (1) = 0 on the projective 3-space. We formulate and illustrate a conjecture on the growth rate of the number of Ein components in dependence on the numbers of the second Chern class. We present a method for calculating the spectra of the above bundles, a recurrent formula, and an explicit formula for computing the number of the spectra of these bundles.
