The algebraic framework introduced in [Koutis, Proc. of the 35th ICALP 2008] reduces several combinatorial problems in parameterized complexity to the problem of detecting multili...
Agreement is an important concept in group interaction, both for computermediated and face-to-face groups. This paper presents a measure of disagreement, D, for groups facing limi...
We study the existence of automatic presentations for various algebraic structures. An automatic presentation of a structure is a description of the universe of the structure by a...
Representation theory is a branch of algebra that allows the study of groups through linear applications, i.e. matrices. Thus problems in abstract groups can be reduced to problems...
Abstract. Unit quaternion is an ideal parameterization for joint rotations. However, due to the complexity of the geometry of S3 group, it’s hard to specify meaningful joint cons...
