Eduardo Renato Caianiello (June 25, 1921 – October 22, 1993) was an Italian physicist. He contributed to scientific research, especially in quantum theory and cybernetics. He was also a pioneer in the theory of neural networks. His Caianiello's equation formalized the theory of Hebbian learning. Caianello founded and directed the Institute of Theoretical Physics of the University of Naples; the Laboratory of Cybernetics of the Consiglio Nazionale delle Ricerche at Arco Felice (Naples), the Faculty of Mathematical, Physical and Natural Sciences of the University of Salerno, the International Institute for Senior Scientific Studies (IIASS) at Vietri sul Mare (Salerno) and the School of Specialization in Cyber and Physical Sciences.

Scientists From Naples
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Copenhagen
Copenhagen ( or .; da, København ) is the capital and most populous city of Denmark, with a proper population of around 815.000 in the last quarter of 2022; and some 1.370,000 in the urban area; and the wider Copenhagen metropolitan area has 2,057,142 people. Copenhagen is on the islands of Zealand and Amager, separated from Malmö, Sweden, by the Øresund strait. The Øresund Bridge connects the two cities by rail and road. Originally a Viking fishing village established in the 10th century in the vicinity of what is now Gammel Strand, Copenhagen became the capital of Denmark in the early 15th century. Beginning in the 17th century, it consolidated its position as a regional centre of power with its institutions, defences, and armed forces. During the Renaissance the city served as the de facto capital of the Kalmar Union, being the seat of monarchy, governing the majority of the present day Nordic region in a personal union with Sweden and Norway ruled by the Danis ...

Hafnian
In mathematics, the hafnian of an adjacency matrix of a graph is the number of perfect matchings in the graph. It was so named by Eduardo R. Caianiello "to mark the fruitful period of stay in Copenhagen (Hafnia in Latin)." The hafnian of a 2n\times 2n symmetric matrix is computed as : \operatorname(A) = \frac \sum_ \prod_^n A_, where S_ is the symmetric group on n= \. Equivalently, : \operatorname(A) = \sum_ \prod_ A_ where \mathcal is the set of all 1-factors (perfect matching In graph theory, a perfect matching in a graph is a matching that covers every vertex of the graph. More formally, given a graph , a perfect matching in is a subset of edge set , such that every vertex in the vertex set is adjacent to exactl ...s) on the complete graph K_, namely the set of all (2n)!/(n!2^n) ways to partition the set \ into n subsets of size 2. The permanent and the hafnian are related as \operatorname(A)=\operatorname\begin & A \\ A^T &\\ \end. References Algebraic ...

University Of Salerno
The University of Salerno ( it, Università degli Studi di Salerno, UNISA) is a university located in Fisciano and in Baronissi, Italy. Its main campus is located in Fisciano while the Faculty of Medicine is located in Baronissi. It is organized in ten faculties. History Salerno's Schola Medica Salernitana was the most important medical school in Europe between the 10th and 13th centuries. Following the rise of university medical schools, it briefly merged with the University of Naples, which moved to Salerno from 1253 to 1258 before returning to Naples and establishing its own medical school there. Meanwhile, the University of Montpellier displaced Salerno as the most prestigious medical school internationally and by the 14th century the latter had ceased to exist. The modern University of Salerno traces its origin to the Istituto Universitario di Magistero “ Giovanni Cuomo”, a teacher training college founded in 1944 with this renowned and ancient tradition in mind.

Consiglio Nazionale Delle Ricerche
The National Research Council (Italian: ''Consiglio Nazionale delle Ricerche, CNR'') is the largest research council in Italy. As a public organisation, its remit is to support scientific and technological research. Its headquarters are in Rome. History The institution was founded in 1923. The first president was Vito Volterra, succeeded by Guglielmo Marconi. The process of improvement of the national scientific research, through the use of specific laws, (see Law 59/1997), affects many research organisations, and amongst them is CNR, whose "primary function is to carry on, through its own organs, advanced basic and applied research, both to develop and maintain its own scientific competitiveness, and to be ready to take part effectively in a timely manner in the strategic fields defined by the national planning system". On 23 December 1987, CNR registered the first Italian internet domain: cnr.it Reorganisation With the issuing of the legislative decree of 30 January 1999, n. ...
