Infant Mental Health Journal: Infancy and Early Childhood, Volume 42, Issue 1, Page 21-34, January/February 2021., 2021 ABSTRACT Parental reflective functioning (PRF) is an important predictor of infant attachment, and interventions that target parent–infant/toddler dyads who are experiencing significant problems have the potential to improve PRF. A range of dyadic interventions have been developed over the past two decades, some of which explicitly target PRF as part ...

Invariant manifolds for finite-dimensional non-archimedean dynamical systems [PDF]
, 2014 Let M be an analytic manifold modelled on an ultrametric Banach space over a complete ultrametric field K. Let f : M → M be an analytic diffeomorphism and p be a fixed point of f .

A Mazur-Ulam problem in non-Archimedean n-normed spaces
Journal of Inequalities and Applications, 2013 In this article, we study the notions of n-isometries in non-Archimedean n-normed spaces over linear ordered non-Archimedean fields and prove the Mazur-Ulam theorem in the spaces. Furthermore, we obtain some properties for n-isometries in non-Archimedean

Non-Archimedean and random HUR-approximation of a Cauchy-Jensen additive mapping
Journal of Inequalities and Applications, 2014 In this paper, using the fixed point and direct methods, we prove the Hyers-Ulam-Rassias approximation (briefly, HUR-approximation) of a Cauchy-Jensen additive (briefly, CJA) functional equation in various normed spaces. MSC:39B52, 39B82, 47H10, 46S10.

Classes of generalized functions with finite type regularities [PDF]
, 2012 We introduce and analyze spaces and algebras of generalized functions which correspond to Hölder, Zygmund, and Sobolev spaces of functions. The main scope of the paper is the characterization of the regularity of distributions that are embedded into the ...

Renormalization method in $p$-adic $\lambda$-model on the Cayley tree [PDF]
, 2014 In this present paper, it is proposed the renormalization techniques in the investigation of phase transition phenomena in $p$-adic statistical mechanics. We mainly study $p$-adic $\l$-model on the Cayley tree of order two.

An axiomatic approach to the non-linear theory of generalized functions and consistency of Laplace transforms [PDF]
, 2011 We offer an axiomatic definition of a differential algebra of generalized functions over an algebraically closed non-Archimedean field. This algebra is of Colombeau type in the sense that it contains a copy of the space of Schwartz distributions.

The Jensen functional equation in non‐Archimedean normed spaces
Journal of Function Spaces, Volume 7, Issue 1, Page 13-24, 2009., 2009 We investigate the Hyers–Ulam–Rassias stability of the Jensen functional equation in non‐Archimedean normed spaces and study its asymptotic behavior in two directions: bounded and unbounded Jensen differences. In particular, we show that a mapping f between non‐Archimedean spaces with f(0) = 0 is additive if and only if ‖f(x+y2)−f(x)+f(y)2‖→0 as max ...

Hyers-Ulam-Rassias stability of the additive-quadratic mappings in non-Archimedean Banach spaces
Journal of Inequalities and Applications, 2012 Using the fixed point and direct methods, we prove the generalized Hyers-Ulam stability of the following additive-quadratic functional equation in non-Archimedean normed spaces r[f(x+y+zs)+f(x−y+zs)+f(x+y−zs)+f(−x+y+zs)]=γf(x)+γf(y)+γf(z), where r, s ...

On maximal immediate extensions of valued division algebras [PDF]
, 2003 We show an extension theorem for strictly contracting bilinear mappings into a spherically complete valued vector space and we apply this result to prove that every maximal valued division algebra having the same characteristic as its residue division ...
