DOI: 10.1007/s11785-018-0878-2
Abstract: The main purpose of this paper is to prove some density results of polynomials in Fock spaces of slice regular functions. The spaces can be of two different kinds since they are equipped with different… read more here.

DOI: 10.2298/fil2420305b
Abstract: Let ? be agiven probability measure supported by a compact subset [a, b] ? R. Given a function ? element of L2([a,b],d?), we proved, under some integrability conditions, that a continuous version of ? can… read more here.

DOI: 10.3390/ma15165715
Abstract: Modelling of quantum cascade laser (QCL) structures, despite a regular progress in the field, still remains a complex task in both analytical and numerical aspects. Computer simulations of such nanodevices require large operating memories and… read more here.
