An infinite natural product [PDF]
Annales Mathematicae Silesianae, 32(1), 247-262 (2018), 2017 We study an infinite countable iteration of the natural product between ordinals. We present an "effective" way to compute this countable natural product, in the non trivial cases the result depends only on the natural sum of the degrees of the factors, where the degree of a nonzero ordinal is the largest exponent in its Cantor normal form ...

Wreath products of cocommutative Hopf algebras [PDF]
arXiv, 2014 We define wreath products of cocommutative Hopf algebras, and show that they enjoy a universal property of classifying cleft extensions, analogous to the Kaloujnine-Krasner theorem for groups. We show that the group ring of a wreath product of groups is the wreath product of their group rings, and that (with a natural definition of wreath products of

Natural products genomics [PDF]
Microbial Biotechnology, 2008 Secondary metabolites (or natural products) are often synthesized by multi‐modular, multi‐domain proteins called non‐ribosomal peptide synthetases (NRPS) and polyketide synthases (PKS). Various well‐known metabolites produced by microorganisms are listed in Table 1, and examples of structures are shown in Fig. 1. In particular, Streptomyces species are
