Abstract (EN): Let C be a smooth projective curve of genus g ¿ 2 over C. Fix n ¿ 1, d ¿ Z. A pair (E, ¿) over C consists of an algebraic vector bundle E of rank n and degree d over C and a section ¿ ¿ H0(E). There is a concept of stability for pairs which depends on a real parameter ¿. Let M¿ (n, d) be the moduli space of ¿-polystable pairs of rank n and degree d over C. We prove that for a generic curve C, the moduli space M¿ (n, d) satisfies the Hodge Conjecture for n ¿ 4. For obtaining this, we prove first that M¿ (n, d) is motivated by C. © 2015 International Press.
