On The Space-Time Fractional Schrödinger Equation with time independent potentials
Saleh Baqer, Lyubomir Boyadjiev
This paper is about the fractional Schrödinger equation (FSE) expressed in terms of the quantum Riesz-Feller space fractional and the Caputo time fractional derivatives. The main f…
Neutron-capture element abundances in the planetary nebula NGC 5315 from deep optical and near-infrared spectrophotometry
S. Madonna, J. García-Rojas, N. C. Sterling +5
We analyze the chemical composition of the planetary nebula (PN) NGC 5315, through high-resolution (R = 40000) optical spectroscopy with UVES at the Very Large Telescope, and mediu…
Identification of Near-Infrared [Se III] and [Kr VI] Emission Lines in Planetary Nebulae
N. C. Sterling, S. Madonna, K. Butler +5
We identify [Se III] 1.0994 micron in the planetary nebula (PN) NGC 5315 and [Kr VI] 1.2330 micron in three PNe, from spectra obtained with the FIRE spectrometer on the 6.5-m Baade…
The word problem for some classes of Adian inverse semigroups
Muhammad Inam
We show that all of the Schützenberger complexes of an Adian inverse semigroup are finite if the Schützenberger complex of every positive word is finite. This enables us to solve t…
Existence of Some Signed Magic Arrays
Abdollah Khodkar, Christian Schulz, Nathan Wagner
We consider the notion of a signed magic array, which is an rectangular array with the same number of filled cells in each row and the same number of filled cells…
