Elliptic Operators with Unbounded Coefficients
(Universita degli studi di Salerno, 2017-04-28)Aim of this manuscript is to give generation results and some Hardy inequalities concerning elliptic operators with unbounded coefficients of the form Au = div(aDu) + F ·Du + V u where V is a real valued function, a(x) = ... -
Estimates for the transition kernel for elliptic operators with unbounded coefficients
(Universita degli studi di Salerno, 2023-02-09)This manuscript is devoted to the study of the qualitative behaviour of the solutions of evolution equations arising from elliptic and parabolic problems on unbounded domains with unbounded coefficients. In particular, ... -
Fractional derivative of the riemann zeta function
(Universita degli studi di Salerno, 2017-05-02)In this work of thesis, the Riemann zeta function was studied by using an unconventional approach. The reason for choosing this approach was to explore the many applications that the Riemann zeta has not only in pure ... -
Highly Stable Multistage Numerical Methods for Functional Equations: Theory and Implementation Issues
(Universita degli studi di Salerno, 2010-08-06)Functional equations provide the best and most natural way to describe evolution in time and space, also in presence of memory. In fact, the spread of diseases, the growth of biological populations, the brain dynamics, ... -
Imbedding and compactness results in some function spaces
(Universita degli studi di Salerno, 2011-03-16)Abstract Nello studio di vari problemi ellittici con soluzioni in spazi di Sobolev S( ) (con o senza peso) definiti su un aperto di Rn, non necessariamente limitato o regolare, spesso risulta necessario stabilire ... -
Le potenzialità dell’e-learning nell’apprendimento della matematica
(Universita degli studi di Salerno, 2011-02-18)La tesi indaga e discute le potenzialità dell’e-learning nell’apprendimento della matematica. Oggi la tecnologia dell’informazione e della comunicazione non è più strettamente legata a qualche quadro teorico. In passato ... -
Lukasiewicz logic: algebras and sheaves
(Universita degli studi di Salerno, 2011-02-21)Classical logic arose from the need to study forms and laws of the human reasoning. But soon, it came out the di culties of classical logic to formalize uncertain events and vague concepts, for which it is not possible ... -
Many valued logics: interpretations, representations and applications
(Universita degli studi di Salerno, 2017-05-10)This thesis, as the research activity of the author, is devoted to establish new connections and to strengthen well-established relations between different branches of mathematics, via logic tools. Two main many valued ... -
MAP/PH/1 systems with group service: performance analysis under different admission strategies
(Universita degli studi di Salerno, 2017-05-04)Recent advances in wireless communication networks led to possibility of multi-rate transmission of information. The queueing theory represents a valid tool to study how the performances of such communication systems can ... -
Measurement of Λc Baryon production in the decay channel Λc → pK0 S in proton-proton and proton-lead collisions with ALICE detector at LHC
(Universita degli studi di Salerno, 2017-05-25)La TPMC risulta essere una procedura molto più sofisticata perché lavora in perfetto accordo con le raccomandazioni dei codici normativi visto che rispetta a pieno i criteri di gerarchia. Questi ultimi, infatti, ... -
Multi-biclustering solutions for classification and prediction problems
(2011-03-19)The search for similarities in large data sets has a relevant role in many scientific fields. It permits to classify several types of data without an explicit information about them. Unfortunately, the experimental ... -
Multi-Value Numerical Modeling for Special Di erential Problems
(Universita degli studi di Salerno, 2015-05-22)The subject of this thesis is the analysis and development of new numerical methods for Ordinary Di erential Equations (ODEs). This studies are motivated by the fundamental role that ODEs play in applied mathematics and ... -
Multiscale wavelet analysis for integral and differential problems
(Universita degli studi di Salerno, 2011-03-08)The object of the present research is wavelet analysis of integral and differential problems by means of harmonic and circular wavelets. It is shown that circular wavelets constitute a complete basis for L2[0; 1] functions, ... -
