This study contributes to the addressing
of the Patent-R&D relationship from a new perspective,
analyzing a crucial yet ignored question: Can more patents
have a negative effect on R&D investment? Offering an
extensive synthesizes of existing theoretical and empirical
literature, we focus on the arguments that might sustain a
negative impact of patents over R&D. The Patent system
seems to have created an incentive to massive patenting
with no perceivable significant(maybe even negative as...

Particular attention is paid to fractional integrals and derivatives, singular, hypersingular and potential operators in variable exponent spaces, pseudodifferential operators in various modern function and distribution spaces, as well as related applications, to mention but a few.
