A combinatorial identity and applications
(Unión Matemática Argentina, 2013-05-29)
An identity for the finite sum 1^N rac{z^n}{q^n-r} is given. Related sums (or series) were studied by Scherk, Clausen, Ramanujan, Shanks, Andrews and others. We use such identity to give new formulas for sum_1^infty ...

On a paper of Dressler and Van de Lune
(Springer, 2020-11-19)
If z∈ C and 1 ≤ n is a natural number then ∑d1d2=n(1-zp1)⋯(1-zpm)zq1e1+⋯+qiei=1, where d1=p1r1⋯pmrm, d2=q1e1⋯qiei are the prime decompositions of d1, d2. This is one of the identities involving arithmetic functions that ...
Shifting identities: new materialities of power and control
Identities, as the materialities that produce them, are changing with the translation of analogue methods of individualization into digital ones. In 2020, with the mobility restrictions related to the COVID-19 pandemic, ...

Jordan Gradings on Associative Algebras
(SPRINGER, 2011)
In this paper we apply the method of functional identities to the study of group gradings by an abelian group G on simple Jordan algebras, under very mild restrictions on the grading group or the base field of coefficients.
