چکیده
Let M be a quadruply-punctured sphere with boundary components A; B; C; D. The SL(2; C)-character variety of M consists of equivalence classes of homomorphisms of 1 (M) ?! SL(2; C) and can be identiied with a quartic hypersurface in C 7. corresponding to representations with tr((A)) = a, tr((B)) = b, tr((C)) = c, tr((D)) = d is a cubic surface in C 3. We determine the singular

Homological Action of the Modular Group on Some Cubic Moduli Spaces
We describe the action of the automorphism group of the complex cubic x + y + x − xyz − 2 on the homology of its fibers. This action includes the action of the mapping class group of a punctured torus on the subvarieties of its SL(2, C) character variety given by fixing the trace of the peripheral element (socalled “relative character varieties”). This mapping class group is isomorphic to PGL(2...
متن کاملThe Algebraic Entropy of the Special Linear Character Automorphisms of a Free Group on Two Generators
In this note, we establish a connection between the dynamical degree, or algebraic entropy of a certain class of polynomial automorphisms of R3, and the maximum topological entropy of the action when restricted to compact invariant subvarieties. Indeed, when there is no cancellation of leading terms in the successive iterates of the polynomial automorphism, the two quantities are equal. In gene...
متن کاملCharacter varieties of once-punctured torus bundles with tunnel number one
We determine the PSL2(C) and SL2(C) character varieties of the once-punctured torus bundles with tunnel number one, i.e. the once-punctured torus bundles that arise from filling one boundary component of the Whitehead link exterior. In particular, we determine ‘natural’ models for these algebraic sets, identify them up to birational equivalence with smooth models, and compute the genera of the ...

متن کاملOn the Algebraic Components of the Sl(2,c) Character Varieties of Knot Exteriors
We show that if a knot exterior satisfies certain conditions, then it has finite cyclic coverings with arbitrarily large numbers of nontrivial algebraic components in their SL2(C)-character varieties (Theorem A). As an example, these conditions hold for hyperbolic punctured torus bundles over the circle (Theorem B). We investigate in more detail the finite cyclic covers of the figure-eight knot...
