Shifted Riccati Procedure: Application to Conformal Barotropic FRW Cosmologies

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
In the case of barotropic FRW cosmologies, the Hubble parameter in conformal time is the solution of a simple Riccati equation of constant coefficients.

Continuous Homomorphisms Defined on (Dense) Submonoids of Products of Topological Monoids

open access: yesAxioms, 2020
We study the factorization properties of continuous homomorphisms defined on a (dense) submonoid S of a Tychonoff product D = ∏ i ∈ I D i of topological or even topologized monoids.

Factoring with Hints [PDF]

open access: yesJournal of Mathematical Cryptology, 2020
Abstract We introduce a new approach to (deterministic) integer factorisation, which could be described in the cryptographically fashionable term of “factoring with hints”: we prove that, for any ϵ > 0, given the knowledge of the factorisations of O

The Category of Factorization

open access: yesApplied Categorical Structures, 2020
We introduce and investigate the category of factorization of a multiplicative, commutative, cancellative, pre-ordered monoid $A$, which we denote $\mathcal{F}(A)$. The objects of $\mathcal{F}(A)$ are factorizations of elements of $A$, and the morphisms in $\mathcal{F}(A)$ encode combinatorial similarities and differences between the factorizations. We

Cycle frames and the Oberwolfach problem

open access: yesAKCE International Journal of Graphs and Combinatorics, 2019
For an integer denotes a graph with uniform edge-multiplicity Let be a subset of positive integers. A 2-regular subgraph of -partite graph containing vertices of all but one partite set is called partial 2-factor, where denotes wreath product and is an ...

On tensor products of nuclear operators in Banach spaces

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2021
The following result of G. Pisier contributed to the appearance of this paper: if a convolution operator ★f : M(G) → C(G), where $G$ is a compact Abelian group, can be factored through a Hilbert space, then f has the absolutely summable set of Fourier ...

Factoring [PDF]

open access: yes, 1994
Factoring, finding a non-trivial factorization of a composite positive integer, is believed to be a hard problem. How hard we think it is, however, changes almost on a daily basis. Predicting how hard factoring will be in the future, an important issue for cryptographic applications of composite numbers, is therefore a challenging task.

The Biopsychosocial Factor [PDF]

open access: yesPsychotherapy and Psychosomatics, 2012
medical practice; rather in significant part it is engaged in special interest advocacy, pursuing and preserving social power’ [ 5 , p. 11]. How could Engel and Holman identify the dangers of special interest groups, as they are sadly known these days [6] , in the 1970s is astonishing. Biomedical reductionism is the key to the success of pharmaceutical

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
