Multivariate exchangeable Archimedean copulas are one of the most popular classes of copulas that are used in actuarial science and finance for modelling risk dependencies and for using them to quantify the magnitude of tail dependence. Owing to the increase in popularity of copulas to measure dependent risks, generating multivariate copulas has become a very crucial exercise. Current methods f...

Let F be a locally compact non-Archimedean field, and let B/F be a division algebra of dimension 4. The JacquetLanglands correspondence provides a bijection between smooth irreducible representations π′ of B× of dimension > 1 and irreducible cuspidal representations of GL2(F ). We present a new construction of this bijection in which the preservation of epsilon factors is automatic. This is don...

We develop the theory of pinchings for non-archimedean analytic spaces. In particular, we show that although affinoid spaces do not have to be affinoid, Hausdorff always exist in category

In this paper, we prove the generalized Hyers-Ulam stability of the quadratic functionalequation$$f(x+y)+f(x-y)=2f(x)+2f(y)$$in non-Archimedean $mathcal{L}$-fuzzy normed spaces.

In the present paper, a partial order on a non- Archimedean fuzzymetric space under the  Lukasiewicz t-norm is introduced and fixed point theoremsfor single and multivalued mappings are proved.

The automaton transformation of infinite words over alphabet Fp = {0, 1, . . . , p− 1}, where p is a prime number, coincide with the continuous transformation (with respect to the p-adic metric) of a ring Zp of p-adic integers. The objects of the study are non-Archimedean dynamical systems generated by automata mappings on the space Zp. Measure-preservation (with the respect to the Haar measure...

Let F/F0 be a quadratic extension of totally real number fields, and let E be an elliptic curve over F which is isogenous to its Galois conjugate over F0. A quadratic extension M/F is said to be almost totally complex (ATC) if all archimedean places of F but one extend to a complex place of M . The main goal of this note is to provide a new construction of a supply of Darmon-like points on E, w...
