Page boy (wedding attendant) arrhae. The coins are presented to the celebrant for a blessing. Page boy (wedding attendant) A page boy is a young male attendant at a wedding or cotillion, a social dance. This type of wedding attendant is less common than it used to be, but is still a way of including young relatives or the children of relatives and friends in a wedding. A page is often seen at British royal weddings. There may be many pages for effect at cotillions. Traditionally, page boys carry the bride's train, especially if the bride is wearing a dress with a long train.
Rank of an elliptic curve formula_1. Then we have the following exact sequence formula_39 Ш formula_40 This shows that the "rank" of formula_41, also called the formula_34-Selmer rank of formula_1, defined as the non-negative integer formula_44 such that formula_45, is an upper bound for the Mordell-Weil rank formula_46 of formula_2. Therefore, if one can compute or obtain an upper bound on formula_34-Selmer rank of formula_1, then one would be able to bound the Mordell-Weil rank on average as well. In "Binary quartic forms having bounded invariants, and the boundedness of the average rank of elliptic curves", Bhargava and Shankar computed the 2-Selmer rank of elliptic
