Blagovest Hristov Sendov (8 February 1932 – 19 January 2020) was a prominent Bulgarian mathematician, academic and public servant. Born in Asenovgrad, he combined a career in mathematical research and higher education with roles in national politics and international diplomacy. Contemporary sources identify him as a notable figure in Bulgaria's post-communist political life and in mathematical circles.
Biographical outline and public offices
Sendov's public career included senior parliamentary posts and a diplomatic posting. He is best known for serving as chairperson of the National Assembly from 1995 to 1997 and subsequently as deputy chairperson until 2002. Later he represented Bulgaria abroad as ambassador to Japan from 2004 to 2009. Sources describe him broadly as a diplomat, mathematician and politician who moved between academic, legislative and diplomatic roles.
Academic work and the Sendov conjecture
As a mathematician, Sendov contributed to the research community and is best known in the discipline for the problem that bears his name: the Sendov conjecture. This conjecture, posed in the late 20th century, concerns the relationship between the zeros of a polynomial and the locations of its critical points; it has attracted much attention and remains an influential question in complex analysis. In addition to research, Sendov participated in scientific administration and higher education throughout his career.
Roles in politics and diplomacy
Sendov's movement into parliamentary leadership came during a period of political transition in Bulgaria. In his legislative roles he presided over parliamentary sessions, contributed to institutional debates and served in deputy leadership after 1997. His later appointment as ambassador reflected a shift toward diplomacy, where he worked to strengthen bilateral ties and represent Bulgarian interests abroad.
Legacy and notable facts
Sendov is remembered for bridging academic life and public service: a researcher whose name is attached to a widely discussed mathematical conjecture and a statesman active in Bulgaria's political life. He died on 19 January 2020 at the age of 87. For readers seeking original references or official records, the Bulgarian spelling and formal notices appear under the Bulgarian spelling of his name.
