Positive solutions of a second-order nonlinear Robin problem involving the first-order derivative

open access: yesAdvances in Difference Equations, 2021
This paper is concerned with the second-order nonlinear Robin problem involving the first-order derivative: { u ″ + f ( t , u , u ′ ) = 0 , u ( 0 ) = u ′ ( 1 ) − α u ( 1 ) = 0 , $$ \textstyle\begin{cases} u''+f(t,u,u^{\prime })=0, \\ u(0)=u'(1)-\alpha u ...

Unconscious Presentation of Object Affordances Evokes a Negative Compatibility Effect [PDF]

open access: yesi-Perception, 2014
According to Gibson's (1979) theory of “affordances”, the environment is constantly bombarding the viewer with a multitude of possible actions. More recently, it has been suggested that the simple viewing of an object can automatically elicit motor plans

An extension theorem for sober spaces and the Goldman topology

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Goldman points of a topological space are defined in order to extend the notion of prime G-ideals of a ring. We associate to any topological space a new topology called Goldman topology. For sober spaces, we prove an extension theorem of continuous maps.

Probing R-parity violation in B-meson decays to a baryon and a light neutralino

open access: yesJournal of High Energy Physics, 2023
We propose a search for B meson decays to a baryon plus missing energy at the Belle II experiment to probe supersymmetry with a GeV-scale lightest neutralino χ ~ 1 0 $$ {\overset{\sim }{\chi}}_1^0 $$ and R-parity violation (RPV).

Riemann zeta zeros and prime number spectra in quantum field theory

open access: yes, 2013
The Riemann hypothesis states that all nontrivial zeros of the zeta function lie in the critical line $\Re(s)=1/2$. Hilbert and P\'olya suggested that one possible way to prove the Riemann hypothesis is to interpret the nontrivial zeros in the light of ...

On the appearance of primes in linear recursive sequences

open access: yesAdvances in Difference Equations, 2005
We present an application of difference equations to number theory by considering the set of linear second-order recursive relations, Un+2(R,Q)=RUn+1−QUn, U0=0, U1=1, and Vn+2(R,Q)=RVn+1−QVn, V0=2,  V1=R, where R and Q are relatively ...

Incommensurate state in a quasi-one-dimensional $S=1/2$ bond-alternating antiferromagnet with frustration in magnetic fields

open access: yes, 2004
We investigate the critical properties of the $S=1/2$ bond-alternating spin chain with a next-nearest-neighbor interaction in magnetic fields. By the numerical calculation and the exact solution based on the effective Hamiltonian, we show that there is a

Automorphisms of Regular Wreath Product 𝑝-Groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
We present a useful new characterization of the automorphisms of the regular wreath product group 𝑃 of a finite cyclic 𝑝-group by a finite cyclic 𝑝-group, for any prime 𝑝, and we discuss an application.
