چکیده

The classical Stallings-Stammbach five-term exact sequence associated with a short exact sequence of groups is shown to exist in a general categorical context. This makes it possible to establish a new result relating low-dimensional homology and central series, which extends a well known result from the theory of groups.

The Low-dimensional Homology of Crossed Modules

This paper is prompted by work of Grandjee an and Ladra on homol-ogy crossed modules. We deene the homology of a crossed module in dimensions one and two via the equivalence of categories with group objects in groupoids. We show that for any perfect crossed module, its second homology crossed module occurs as the kernel of its universal central extension as deened by Norrie. Our rst homology is...

Some aspects of cosheaves on diffeological spaces

We define a notion of cosheaves on diffeological spaces by cosheaves on the site of plots. This provides a framework to describe diffeological objects such as internal tangent bundles, the Poincar'{e} groupoids, and furthermore, homology theories such as cubic homology in diffeology by the language of cosheaves. We show that every cosheaf on a diffeological space induces a cosheaf in terms of t...

Comparison of the Lipophosphoglycan 3 Gene of the Lizard and Mammalian Leishmania: A Homology Modeling

Background: Lipophosphoglycan 3 (LPG3) is required for the LPG assembly, a well known virulent molecule. In this study, the LPG3 gene of the lizard and mammalian Leishmania species were cloned and sequenced. A three-dimensional structure (3D) for the target sequence was also predicted by comparative (homology) modeling. Materials and Methods: An optimization PCR amplification was performed o...

Applying Near-Optimal Alignments to Protein Structure Prediction

The prediction of three-dimensional protein structures from onedimensional amino acid sequence information is an important and interesting problem, as much can be learned about a protein’s function from the way that it is folded. There are many different ways to approach this problem, but they all tend to fall into three basic categories: homology modeling, fold recognition, and ab initio predi...

Homotopy, Homology, and Gl 2

We define weak 2-categories of finite dimensional algebras with bimod-ules, along with collections of operators O (c,x) on these 2-categories. We prove that special examples Op of these operators control all homological aspects of the rational representation theory of the algebraic group GL2, over a field of positive characteristic. We prove that when x is a Rickard tilting complex, the operato...
