Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Banach space theory and operator algebras form two pillars of modern functional analysis, linked by the study of bounded linear operators on complete normed spaces. Banach spaces provide a flexible ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

Banach space theory investigates the structure of complete normed vector spaces and the geometric characteristics that govern their behaviour. Central notions include convexity, smoothness and the ...
