The Kerala School of Astronomy and Mathematics was a late medieval school that originated in what is now Kerala, India. Flourishing between the 14th and 16th centuries, it made significant contributions to mathematical concepts such as infinite series expansions for trigonometric functions. Key figures included Madhava of Sangamagrama, along with his successors Parameshvara and Jyeshtadeva. The school is noted for its pioneering work in developing methods that anticipated later developments in calculus and the formulation of infinite series, particularly regarding the sine function.

The Kerala School's body of work was primarily transmitted through palm leaf manuscripts, which have been crucial in preserving their mathematical and astronomical insights. Their notable contributions include early calculations that presaged elements of what would later become integral to calculus, specifically infinite series expansions for trigonometric functions such as the sine function. These discoveries were documented in seminal texts like “Yuktibhasa.” The school's significance was rejuvenated through the efforts of scholars like C.T. Rajagopal, K.V. Sarma, George Joseph, and Arun Bala, who played a pivotal role in bringing these historical contributions to light. Recent initiatives have focused on digitally preserving these manuscripts, thereby increasing their accessibility for research and study.

The Kerala School's development cannot be fully understood without considering the regional trade networks of Kerala, which facilitated knowledge exchange that likely influenced their mathematical advancements. Additionally, the school's astronomical calculations were deeply intertwined with Vedic astrology traditions, reflecting an interdisciplinary approach to their scholarly work.

One viewpoint emphasizes how the Kerala School's advancements remained largely obscured until rediscovered by historians of mathematics in the modern era. Another perspective suggests that while these works were significant within India, they may have indirectly influenced European mathematicians through trade routes and cultural exchanges. Conversely, some scholars highlight the school's role in demonstrating the independent development of sophisticated mathematical ideas outside Europe. A particular focus is on Madhava's contributions to π and infinite series for trigonometric functions, underscoring his pioneering work in these areas. Additionally, the efforts of successors like Parameshvara and Jyeshtadeva are recognized as significant extensions of this foundational work.

There is debate over whether the Kerala School's achievements were developed independently or influenced by other mathematical traditions, such as those from the Islamic world. Controversy exists regarding the precise timeline and sequence of discoveries made by the school compared to similar developments in Western mathematics. Questions also arise concerning how their knowledge was transmitted and preserved, given the lack of a continuous written tradition. Moreover, disputes persist over the interpretation of primary sources and their translations.
