Asphericity of symmetric presentations

Fulvia Spaggiari (2006)

Publicacions Matemàtiques

Similarity:

Using the notion of relative presentation due to Bogley and Pride, we give a new proof of a theorem of Prishchepov on the asphericity of certain symmetric presentations of groups. Then we obtain further results and applications to topology of low-dimensional manifolds.

On the Toëplitz corona problem.

Eric Amar (2003)

Publicacions Matemàtiques

Similarity:

The aim of this note is to characterize the vectors g = (g, . . . ,g) of bounded holomorphic functions in the unit ball or in the unit polydisk of C such that the Corona is true for them in terms of the H Corona for measures on the boundary.
