Cohomology of preimages with local coefficients
Daciberg Lima Goncalves, Peter Wong
Let M,N and B\subset N be compact smooth manifolds of dimensions n+k,n and \ell, respectively. Given a map f from M to N, we give homological conditions under which g^{-1}(B) has n…
Some quadratic equations in the free group of rank 2
Daciberg Goncalves, Elena Kudryavtseva, Heiner Zieschang
For a given quadratic equation with any number of unknowns in any free group F, with right-hand side an arbitrary element of F, an algorithm for solving the problem of the existenc…
A classification of special 2-fold coverings
Anne Bauval, Daciberg L Goncalves, Claude Hayat +1
Starting with an O(2)-principal fibration over a closed oriented surface F_g, g>=1, a 2-fold covering of the total space is said to be special when the monodromy sends the fiber SO…
