It is with profound sadness that we learn of the passing of our cherished friend and esteemed colleague, Prof. Jacob Palis. His remarkable legacy serves as an enduring beacon of inspiration to the global scientific community, especially within the developing world.
Prof. Palis has made outstanding contributions to the field of mathematics, particularly in dynamical systems and differential equations. His groundbreaking work earned him numerous prestigious awards from national and international organisations.
His contribution to TWAS was marked by great devotion and visionary leadership. He held key roles since his induction into TWAS membership in 1991, including chairing the Membership and Awards Committees and serving on the Policy Development and Future Actions (PDFA) committee and other TWAS committees from 1991 to 2000, serving as TWAS secretary-general from 2001 to 2006, and as president from 2007 to 2012, followed by a term as Immediate Past President. Throughout these roles, his strong commitment and guidance significantly shaped the future of the Academy.
During my two decades of collaboration with Jacob, particularly in my role as TWAS executive director, I witnessed his profound impact on the growth and success of the Academy. His passion for enhancing TWAS's South-South postgraduate education programmes was remarkable. Under his stewardship, the fellowship programs flourished, reaching nearly 300 fellowships annually. His leadership enabled hosting countries such as Brazil, China, India, Malaysia, Mexico, Pakistan, and South Africa to provide comprehensive support, creating one of the most extensive fellowship programs in the developing world.
Palis also championed the decentralisation of TWAS activities by empowering regional offices to take charge of fostering young scientific talent. With his guidance, TWAS Regional Partners have been regularly hosting regional conferences for young scientists, and selecting the most accomplished scientists under the age of 40 as TWAS Young Affiliates.
Prof. Palis's legacy was driven by three core passions: pioneering frontier mathematical research, fostering international collaboration in mathematics and science, and supporting young scientists and postgraduate students in low and middle-income countries (LMICs). His work has been a beacon of hope and inspiration, guiding numerous initiatives that emphasise the importance of research and education in the growth and development of these countries.
In mathematics, especially dynamical systems, Prof. Palis made profound contributions, including the famous Palis Conjecture. His pioneering exploration of complex systems enriched the mathematical world and impacted fields like physics and biology. His work continues to inspire mathematicians worldwide, reflecting his enduring influence.
Perhaps one of his most admirable pursuits was his unwavering support for young scientists and postgraduate students in LMICs. Recognising the challenges facing scientists in these regions, he worked tirelessly to create opportunities and platforms for young minds to thrive and contribute to the global body of scientific knowledge. Through mentorship programs, scholarships, and global networking platforms, he helped to ensure that young mathematicians and scientists were empowered to pursue their dreams and emerge as future leaders.
In memory of our cherished leader and friend, let us continue his vision of a harmonious and thriving global scientific community, where the developing world plays an equal role in advancing science and its applications to real-world problems.
By emulating his passion and dedication, we can honour his memory and continue the work he so passionately followed, ensuring that his vision of a brighter, more-connected world becomes a reality.
Our heartfelt condolences to Jacob’s family and all his friends and colleagues.
Mohamed Hassan,
Immediate Past President of TWAS
