Gwalior preserves zero within place-value numerals

A 21 December 2012 article uses the end of a Long Count cycle to explain Maya calendrical mathematics.

The 260-day ritual count and other interlocking cycles demonstrate modular thinking and systematic enumeration.

Dots, bars and a shell-shaped zero made it possible to represent large numbers compactly.

It explains that the calendar's cycle ending was a mathematical rollover, not a prediction of the world's destruction.

The 7 October 2013 article examines an Indian temple inscription containing circular zero symbols.

It emphasizes that the so-called Arabic numerals reached Europe through a longer Indian-Arabic chain of transmission.

The publication explores possible cultural relationships while avoiding the claim that philosophy alone mechanically produced mathematical zero.

The IMU recognized her work on the dynamics and geometry of Riemann surfaces and moduli spaces.

His award for dynamical systems marked a milestone for mathematical research in Latin America.

The laureates' careers crossed Iran, Brazil, India, Europe and North America, showing the mobility and unequal geography of research institutions.
