Homological Methods in Algebra [PDF]
, 2019 In this thesis, we apply homological methods to the study of groups in two ways: firstly, we generalise the results of [12] to a more general class of categories than posets, including finite groups which satisfy a particular cohomological condition. We

Simplicial methods and the homology of groups. [PDF]
, 1997 PhDThis thesis generalizes the simplicial methods of defining derived functors and proves characterization theorems about them. In particular, we show that our methods also generalize an alternative way of defining derived functors, We use our ...

Modules of type FP2 over the integral group algebra of a metabelian group
, 2021 We establish a su‰cient condition for some modulesMover the group algebraZ½G to be of homological type FP2, whereGis a finitely generated split extension of abelian groups.This generalizes a result of Bieri and Strebel [6] whenMis the trivial moduleZand ...

Embedding homological properties of metabelian discrete groups: the general case
, 2015 We extend a result in [11] which showed that for each m every finitely generated metabelian group G embeds in a quotient of a metabelian group of homological type FPm and furthermore that G embeds in a metabelian group of type FP4.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Dieudonné theory for Faltings' strict ϭ-modules [PDF]
, 2005 The theory of group schemes and their liftings to mixed characteristic valuation rings is well-developed. In [Fal02], a new equi-characteristic analogue of group schemes, known as group schemes with strict ๕-action, or strict ๕-modules, was proposed and ...

Abelian-by-polycyclic groups of homological type FP3
, 2015 We show that abelian-by-polycyclic groups of homological type FP3 are virtually nilpotent-by-abellan. this generalizes earlier results of C. J. B. Brookes.

Structure‐forward targeting of claudins with synthetic binders
FEBS Letters, EarlyView.Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.
