36 p, 630.5 KB Bielliptic quotient curves of X0(N) / Bars Cortina, Francesc (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Kamel, Mohamed (Cairo University. Department of Mathematics) ; Schweizer, Andreas (Kongju National University. Department of Mathematics Education (South Korea))
Let N ≥ 1 be a non-square free integer and let WN be a nontrivial subgroup of the group of the Atkin-Lehner involutions of X0(N) such that the modular curve X0(N)=WN has genus at least two. We determine all pairs (N;WN) such that X0(N)=WN is a bielliptic curve and the pairs (N;WN) such that X0(N)=WN has an innite number of quadratic points over Q.

28 p, 1.4 MB Orbitally symmetric systems with applications to planar centers / Bastos, Jefferson L. R. (Universidade Estadual Paulista Júlio de Mesquita Filho. Departamento de Matemática) ; Buzzi, Claudio (Universidade Estadual Paulista Júlio de Mesquita Filho. Departamento de Matemática) ; Torregrosa, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We present a generalization of the most usual symmetries in differential equations known as the time-reversibility and the equivariance ones. We check that the typical properties are also valid for the new definition that unifies both. [...]

The dry period is decisive for the milking performance of dairy cows. The promptness of mammary gland involution at dry-off affects not only the productivity in the next lactation, but also the risk of new intra-mammary infections since it is closely related with the activity of the immune system.

28 p, 511.9 KB Smooth linearisation of planar periodic maps / Cimà, Anna (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mañosas Capellades, Francesc (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Ortega, Rafael (Universidad de Granada. Departamento de Matemática Aplicada)
The celebrated Kerékjártó theorem asserts that planar continuous periodic maps can be continuously linearised. We prove that for each k ∈ {1, 2,. . . , ∞}, Ck-planar periodic maps can be Ck-linearised.

Departament de Matemàtiques) ; Mañosas Capellades, Francesc (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Ortega, Rafael (Universidad de Granada. Departamento de Matemática Aplicada)
The celebrated Kerékjártó Theorem asserts that planar continuous periodic maps can be continuously linearized. We prove that C^1-planar involutions can be C^1-linearized.

15 p, 144.9 KB Reversibility in the diffeomorphism group of the real line / O'Farrell, Anthony G. (National Univeristy of Ireland Maynooth. Department of Mathematics) ; Short, Ian (Centre for Mathematical Sciences (Gran Bretanya). Department of Pure Mathematics and Mathematical Statistics)
An element of a group is said to be reversible if it is conjugate to its inverse. We characterise the reversible elements in the group of diffeomorphisms of the real line, and in the subgroup of order preserving diffeomorphisms.
