The concept of 'panchayati raj' system for managing transportation was not developed by any of the mentioned Indian mathematicians.

Aryabhata is considered the father of Indian Cosmology. He was an Indian mathematician and astronomer who lived in the 5th century CE. He is best known for his work on the heliocentric model of the solar system, which he proposed in his book, the Aryabhatiya.

Brahmagupta was an Indian astronomer and mathematician who lived in the 7th century CE. He is best known for his work on the Brahmasphuta Siddhanta, which contains a detailed exposition of the cyclical cosmology, in which the universe is seen as expanding and contracting in cycles.

Bhaskara II was an Indian astronomer and mathematician who lived in the 12th century CE. He is best known for his work on the Siddhānta Shiromani, which contains a detailed exposition of the infinite and eternal universe, in which the universe is seen as having no beginning or end.

Varāhamihira was an Indian astronomer and astrologer who lived in the 6th century CE. He is best known for his work on the Brihat Samhita, which contains a detailed exposition of the multiple universes, in which the universe is seen as being made up of an infinite number of universes.
