Fabien Morel is a French algebraic geometer and key developer of A¹ homotopy theory with Vladimir Voevodsky.
 Among his accomplishments is the proof of the Friedlander conjecture, and the proof of the complex case of the Milnor conjecture stated in Milnor's 1983 paper 'On the homology of Lie groups made discrete'.
 This result was presented at the Second Abel Conference, held in January–February 2012.
In algebraic geometry, the "h" topology is a Grothendieck topology introduced by Vladimir Voevodsky to study the homology of schemes.
 It has several variants, such as the "qfh" and "cdh" topologies.
Successful aging (American English) or successful ageing (British English) refers to physical, mental and social well-being in older age.
 The concept of successful aging can be traced back to the 1950s, and was popularized in the 1980s.
 It reflects changing view on aging in Western countries, where a stigma associated with old age (see ageism) has led to considering older people as a burden on society.
 Consequently, in the past most of the scientists have been focusing on negative aspects of aging or preventing the decline of youth.
In India, the Child Sex Ratio is defined as the number of females per thousand males in the age group 0–6 years in a human population.
 Thus it is equal to 1000 x the reciprocal of the sex ratio (ratio of males to females in a population) in the same age group, i.e. under age seven.
 Obviously, an imbalance in this age group will extend to older age groups in future years.
 Currently, the ratio of males to females is generally significantly greater than 1, i.e. there are more boys than girls.
In algebraic geometry and algebraic topology, a branch of mathematics, A homotopy theory is a way to apply the techniques of algebraic topology, specifically homotopy, to algebraic varieties and, more generally, to schemes.
 The theory is due to Fabien Morel and Vladimir Voevodsky.
 The underlying idea is that it should be possible to develop a purely algebraic approach to homotopy theory by replacing the unit interval [0, 1] , which is not an algebraic variety, with the affine line A , which is.
 The theory requires a substantial amount of technique to set up, but has spectacular applications such as Voevodsky's construction of the derived category of mixed motives and the proof of the Milnor and Bloch-Kato conjectures.
In mathematics, the norm residue isomorphism theorem is a long-sought result relating Milnor "K"-theory and Galois cohomology.
 The result has a relatively elementary formulation and at the same time represents the key juncture in the proofs of many seemingly unrelated theorems from abstract algebra, theory of quadratic forms, algebraic K-theory and the theory of motives.
 The theorem asserts that a certain statement holds true for any prime formula_1 and any natural number formula_2.
 John Milnor speculated that this theorem might be true for formula_3 and all formula_2, and this question became known as Milnor's conjecture.
 The general case was conjectured by Spencer Bloch and Kazuya Kato and became known as the Bloch–Kato conjecture or the motivic Bloch–Kato conjecture to distinguish it from the Bloch–Kato conjecture on values of "L"-functions.
 The norm residue isomorphism theorem was proved by Vladimir Voevodsky using a number of highly innovative results of Markus Rost.
Aleksandr (Alexander) Semenovich Kronrod (Russian: Алекса́ндр Семёнович Кронро́д ) (October 22, 1921 – October 6, 1986) was a Soviet mathematician and computer scientist, best known for the Gauss-Kronrod quadrature formula which he published in 1964.
 Earlier, he worked on computational solutions of problems emerging in theoretical physics.
 He is also known for his contributions to economics, specifically for proposing corrections and calculating price formation for the USSR.
 Later, Kronrod gave his fortune and life to medicine to care for terminal cancer patients.
 Kronrod is remembered for his captivating personality and was admired as a student, teacher and leader.
Sexuality in older age concerns the sexual drive, sexual activity and overall sexuality of people in middle age and those in old age, and the social perceptions about sexuality in older age.
 Older people engage in a variety of sexual acts from time to time for a variety of reasons.
 While the human body has some limits on the maximum age for reproduction, sexual activity can be performed or experienced well into the later years of life.
 Sexuality in older age is often considered a taboo, and this can affect how older individuals experience their sexuality.
Vladimir Alexandrovich Voevodsky ( ; Russian: Влади́мир Алекса́ндрович Воево́дский , 4 June 1966 - 30 September 2017) was a Russian mathematician.
 His work in developing a homotopy theory for algebraic varieties and formulating motivic cohomology led to the award of a Fields Medal in 2002.
 He is also known for the proof of the Milnor conjecture and motivic Bloch-Kato conjectures and for the univalent foundations of mathematics and homotopy type theory.
Love, Sex, and Aging is a 1984 book on sexuality in older age by medical writer Edward M. Brecher and the editors of Consumer Reports.
 The book presents survey research describing the attitudes and experiences of older people in the United States based on a 1977 Consumer Reports survey of over 4000 people.
 One reason for the study was to demonstrate that older people can have healthy sex lives.
 At the time and place of publication, this topic was not commonly discussed.
