Finitely presented groups and the Whitehead nightmare
Daniele Ettore Otera, Valentin Poenaru
We define a `nice representation' of a finitely presented group G as being a non-degenerate essentially surjective simplicial map f from a `nice' space X into a 3-complex associate…
All finitely presented groups are QSF
Valentin Poenaru
This is the third and last of three papers containing the complete proof that all finitely presented groups are QSF.
Geometric simple connectivity and finitely presented groups
Valentin Poenaru
This is the second of a Series of three papers, the first one published in Geom Dedicata 167 p. 91-121 (2013), proving that all finitely presented groups are QSF.
Discrete symmetry with compact fundamental domain, and geometric simple connectivity - A provisional Outline of work in Progress -
Valentin Poenaru
We show that a certain geometric property, the QSF introduced by S. Brick and M. Mihalik, is universally true for {\ibf all} finitely presented groups . One way of defining this…
On the 3-Dimensional Poincaré Conjecture and the 4-Dimensional Smooth Schoenflies Problem
Valentin Poenaru
This is the announcement of an alternative approach to the 3-dimensional Poincaré Conjecture, different from Perelman's big and spectacular breakthrough. No claim concerning the ot…
