Mikhael Gromov is a famous mathematician. He was born in 1943 in the Soviet Union. When he was nine, his mother gave him a math book. This book made him very curious about math. He studied hard and earned many degrees.

In the 1970s, he wanted to move to a new country. He moved to New York to work at Stony Brook. Later, he moved to France. He even became a French citizen in 1992. Today, he works at several big schools.

Mikhael studies geometry. Geometry is the study of shapes and spaces. He looks at shapes in a special way. He studies how they look from far away. This is often called a "soft" or "coarse" view. He also thinks about how the brain works.

He has won many awards. In 2009, he won the Abel Prize. This is a very big prize for math. He won it for his new ideas in geometry. His work helps us understand how shapes can bend and grow. He also studies how math ideas change over time.

Mikhael Leonidovich Gromov is a highly influential mathematician. He is recognized for his revolutionary work in geometry, analysis, and group theory. Born on December 23, 1943, in Boksitogorsk, Soviet Union, Gromov grew up in a family of medical professionals. His parents were both pathologists. His mother, Lea, was a medical doctor in the Soviet Army. She even had to leave the front lines of World War II to give birth to him. At age nine, a book called "The Enjoyment of Mathematics" by Hans Rademacher and Otto Toeplitz sparked his lifelong curiosity.

Gromov's academic journey began at Leningrad State University. He earned his master's degree in 1965 and his doctorate in 1969. He completed his postdoctoral thesis in 1973 under the guidance of Vladimir Rokhlin. His career was shaped by the political constraints of the Soviet Union. In 1970, he was invited to present at the International Congress of Mathematicians in Nice, France. However, the Soviet government prevented him from leaving the country. This led him to consider emigrating from the age of 14. He eventually moved to New York in 1974 to work at Stony Brook University.

Today, Gromov holds several prestigious positions. He is a permanent member of the Institut des Hautes Études Scientifiques in France. He is also a professor at New York University and the Courant Institute of Mathematical Sciences. In 1992, he adopted French citizenship. His mathematical style is unique because it often uses a "coarse" or "soft" viewpoint. Instead of focusing on tiny details, he analyzes asymptotic or large-scale properties of shapes. This approach allows him to see how spaces behave when viewed from a distance. He also explores mathematical biology and the structure of the human brain.

One of Gromov's most significant contributions is the development of the h-principle. This theory was motivated by the work of mathematicians like John Nash and Nicolaas Kuiper. The h-principle provides a way to solve certain types of geometric problems. By using the theory of microflexible sheaves, Gromov proved they satisfy an h-principle on open manifolds. This allowed him to prove that positively and negatively curved Riemannian metrics exist on any open manifold. This work stands in contrast to other theorems that place strict limits on such shapes.

Gromov also made major breakthroughs in Riemannian geometry. In 1978, he introduced the concept of almost flat manifolds. He showed that if a manifold has sectional curvatures very close to zero, it must be a specific type of shape called a nilmanifold. This discovery relied on replaying the proofs of the Bieberbach theorem and the Margulis lemma. He also worked on the existence of positive scalar curvature. Alongside Blaine Lawson, he showed that certain shapes, like the torus, cannot support this kind of curvature. This helped resolve long-standing mathematical conjectures.

Another major area of his research involves the concentration of measure phenomena. Working with Vitali Milman, Gromov formulated how certain measures behave in high dimensions. They defined a "Lévy family" to describe a sequence of metric measure spaces. In these families, sets can be "thickened" to include almost every point in the space. This concept is very similar to the law of large numbers in probability. Their work identified examples in Riemannian manifolds where specific mathematical values diverge to infinity. This research continues to be studied by other mathematicians today.

Gromov's influence extends across many different scientific fields. His work on harmonic maps helped extend theories into the setting of metric spaces. This led to new results regarding discrete groups and the study of lattices. His insights have even touched upon the way scientific ideas evolve over time. In 2009, he was awarded the Abel Prize for his revolutionary contributions to geometry. This is one of the highest honors in the field of mathematics. His legacy remains central to modern geometry and analysis.
