An Introduction to The Royan Human Ovarian Tissue Bank

From December 2000 until 2010, the researchers at Royan Institute conducted a wide range of investigations on ovarian tissue cryopreservation with the intent to provide fertility preservation to cancer patients that were considered to be candidates for these services. In 2010, Royan Institute established the Royan Human Ovarian Tissue Bank as a subgroup of the Embryology Department. Since its i...

An Introduction to Heisenberg Groups

for all x, x ∈ R. Also, Tx is the identity operator only when x = 0, and thus the correspondence x 7→ Tx provides an isomorphic embedding of R , as an abelian group, into the group of invertible linear operators on the vector space of continuous functions with compact support on R under the binary operation composition. Of course there are numerous other vector spaces of functions on R that one...

An introduction to arithmetic groups

Arithmetic groups are groups of matrices with integral coefficients. They first appeared in the work of Gauss, Minkowski and others on the arithmetic theory of quadratic forms. Their reduction theory consists in showing that, after a linear change of variables with integral coefficients, any quadratic form can be forced to satisfy an appropriate set of inequalities. Around 1940, Siegel develope...
