    The β-Meixner model 

    Ferreiro Castilla, Albert; Schoutens, Wim; Centre de Recerca Matemàtica (2011)

    We propose to approximate the Meixner model by a member of the B-family introduced in [Kuz10a]. The advantage of such approximations are the semi-explicit formulas for the running extrema under the B-family processes which ...

    Onomástica china de la 'Historia de las cosas más notables, ritos y costumbres del gran Reyno de la China', de Juan González de Mendoza 

    Ramírez, Laureano (2023)

    'La Historia de las cosas más notables, ritos y costumbres del gran Reyno de la China', de fray Juan González de Mendoza, tuvo gran difusión en la Europa de la Edad Moderna y marcó, gracias a su popularidad, un punto de ...

    A geometric mechanism of diffusion: Rigorous verification in a priori unstable Hamiltonian systems 

    Delshams, Amadeu; Huguet, Gemma; Centre de Recerca Matemàtica (2010)

    In this paper we consider a representative a priori unstable Hamiltonian system with 2+1/2 degrees of freedom, to which we apply the geometric mechanism for diffusion introduced in the paper Delshams et al., Mem.Amer.Math. ...

    Weighted Hardy spaces for the unit disc: approximation properties 

    Boivin, André; Gauthier, Paul M.; Zhu, Changzhong; Centre de Recerca Matemàtica (2007)

    In this paper we study basic properties of the weighted Hardy space for the unit disc with the weight function satisfying Muckenhoupt's (Aq) condition, and study related approximation problems (expansion, moment and ...

    Subgroups of small index in Aut(Fn) and Kazhdan's property (T) 

    Bogopolski, O.; Vikentiev, Ruslan; Centre de Recerca Matemàtica (2007)

    We give a series of interesting subgroups of finite index in Aut(Fn). One of them has index 42 in Aut(F3) and infinite abelianization. This implies that Aut(F3) does not have Kazhdan's property (T) (see [3] and [6] for ...

    Semipurity of tempered Deligne cohomology 

    Burgos Gil, José Ignacio; Centre de Recerca Matemàtica (2007)

    In this paper we define the formal and tempered Deligne cohomology groups, that are obtained by applying the Deligne complex functor to the complexes of formal differential forms and tempered currents respectively. We then ...

    Non compact euclidean cone 3-manifolds with cone angles less than 2∏ 

    Cooper, D.; Porti, Joan; Centre de Recerca Matemàtica (2006)

    We study of noncompact Euclidean cone manifolds with cone angles less than c<2π and singular locus a submanifold. More precisely, we describe its structure outside a compact set. As a corol lary we classify those with cone ...

    Spot inversion in the Heston model 

    Baño Rollin, Sebastian del; Centre de Recerca Matemàtica (2008)

    We analyse the Heston stochastic volatility model under an inversion of spot. The result is that under the appropriate measure changes the resulting process is again a Heston type process whose parameters can be explicitly ...

    Epireflections and supercompact cardinals 

    Bagaria, Joan; Casacuberta, Carles; Mathias, A. R. D.; Centre de Recerca Matemàtica (2007)

    We prove that, under suitable assumptions on a category C, the existence of supercompact cardinals implies that every absolute epireflective class of objects of C is a small-orthogonality class. More precisely, if L is a ...

    Projective modules over the Gerasimov-Sakhaev counterexample 

    Dubrovin, Nikolay; Prihoda, Pavel; Puninski, Gena; Centre de Recerca Matemàtica (2007)

    We investigate the structure of the so-called Gerasimov- Sakhaev counterexample, which is a particular example of a universal localization, and classify (both finitely and infinitely generated) projective modules over it.

    Generic optimality conditions for semi-algebraic convex programs 

    Bolte, Jerôme; Daniilidis, Aris; Lewis, Adrian S.; Centre de Recerca Matemàtica (2010)

    We consider linear optimization over a nonempty convex semi-algebraic feasible region F. Semidefinite programming is an example. If F is compact, then for almost every linear objective there is a unique optimal solution, ...

    Generalized multiresolution analyses with given multiplicity functions 

    Baggett, Lawrence W.; Larsen, Nadia S.; Merrill, Kathy D.; Packer, Judith A.; Raeburn, Iain; Centre de Recerca Matemàtica (2008)

    Generalized multiresolution analyses are increasing sequences of subspaces of a Hilbert space H that fail to be multiresolution analyses in the sense of wavelet theory because the core subspace does not have an orthonormal ...

    Horospheres in hyperbolic geometry 

    Gallego Gómez, Eduardo; Reventós, Agustí; Centre de Recerca Matemàtica (2008)

    In this paper we investigate the role of horospheres in Integral Geometry and Differential Geometry. In particular we study envelopes of families of horocycles by means of "support maps". We define invariant "linear ...
