Mapping Class Groups of Compression Bodies and 3-Manifolds
We analyze the mapping class group Hx(W ) of automorphisms of the exterior boundary W of a compression body (Q,V ) of dimension 3 or 4 which extend over the compression body. Here V is the interior boundary of the compression body (Q,V ). Those automorphisms which extend as automorphisms of (Q,V ) rel V are called discrepant automorphisms, forming the mapping class group Hd(W ) of discrepant au...
متن کاملA characterization of the duality mapping for convex bodies
We characterize the duality of convex bodies in d-dimensional Euclidean vector space, viewed as a mapping from the space of convex bodies containing the origin in the interior into the same space. The question for such a characterization was posed by Vitali Milman. Sufficient for a characterization, up to a trivial exception and the composition with a linear transformation, is the property that...
متن کاملMultilocus analysis for gene-centromere mapping using first polar bodies and secondary oocytes.
Polar body and oocyte typing is a new technique for gene-centromere mapping and for generating female linkage maps. A maximum likelihood approach is presented for ordering multiple markers relative to the centromere and for estimating recombination frequencies between markers and between the centromere and marker loci. Three marker-centromere orders are possible for each pair of markers: two or...
متن کاملShared Mapping of Own and Others' Bodies in Visuotactile Bimodal Area of Monkey Parietal Cortex
Parietal cortex contributes to body representations by integrating visual and somatosensory inputs. Because mirror neurons in ventral premotor and parietal cortices represent visual images of others' actions on the intrinsic motor representation of the self, this matching system may play important roles in recognizing actions performed by others. However, where and how the brain represents othe...
متن کاملVirtual infant’s online acquisition of vowel categories and their mapping between dissimilar bodies
In order to understand how humans learn speech imitation without access to detailed articulatory data of other talkers, simulated speech acquisition experiments between two virtual agents were carried out with the goal of maintaining the interaction between the two as natural as possible. As an outcome, a novel model of infants’ vowel acquisition is presented. In the experimental setup, a virtu...
