A complete presentation of $(\mathbb{C}\mbox{[X]},\circ)$
Barbu Rudolf Berceanu
We recall the fundamental theorem of J.F. Ritt, with a stress on the action of the affine group and canonical forms of complex polynomials. Then we give a complete presentation of…
Restricted configuration spaces
Barbu Rudolf Berceanu
Finitely many hypersurfaces are removed from unordered configuration spaces of points in to obtain a fibration over unordered configuration spaces of complex…
Strong stability and shifted stability for the cohomology of configuration spaces
Barbu Berceanu, Muhammad Yameen
Homological stability for unordered configuration spaces of connected manifolds was discovered by Th. Church and extended by O. Randal-Williams and B. Knudsen: $H_i(C_k(M);\mathbb{…
On the geometry and topology of partial configuration spaces of Riemann surfaces
Barbu Berceanu, Daniela Anca Macinic, Stefan Papadima +1
We examine complements (inside products of a smooth projective complex curve of arbitrary genus) of unions of diagonals indexed by the edges of an arbitrary simple graph. We use Gy…
Relative Garside elements of Artin monoids
Usman Ali, Barbu Berceanu, Zaffar Iqbal
We introduce a relative Garside element, the quotient of the corresponding Garside elements G1 and G2, for a pair of Artin monoids associated to Coxeter graphs Gamma1 and Gamma2, t…
Cohomology of 3-points configuration spaces of complex projective spaces
Samia Ashraf, Barbu Berceanu
We compute the Betti numbers and describe the cohomology algebras of the ordered and unordered configuration spaces of three points in complex projective spaces, including the infi…
