A first-price sealed-bid auction (FPSBA) is a common type of auction. It is also known as blind auction. [1] In this type of auction, all bidders simultaneously submit sealed bids so that no bidder knows the bid of any other participant. The highest bidder pays the price that was submitted. [2]: p2 [3]
Each of the bids increases the price of the item by a small amount, such as one penny (0.01 USD, 1¢, or 0.01 GBP, 1p; hence the name of the auction), and extends the time of the auction by a few seconds. Bid prices vary by site and quantity purchased at a time, but generally cost 10–150 times the price of the bidding increment.

Online auctions often use an equivalent version of Vickrey's second-price auction wherein bidders provide proxy bids for items. A proxy bid is an amount an individual values some item at. The online auction house will bid up the price of the item until the proxy bid for the winner is at the top.
One possible proof outline is as follows. If is finite, it suffices to take () = ().If is not finite, consider the finite sum () = where is a finite subset of .While the () may not converge as F approaches E, one may subtract well-chosen rational functions with poles outside of (provided by Runge's theorem) without changing the principal parts of the () and in such a way that convergence is ...
A closely related summation method, also called Mittag-Leffler summation, is given as follows (Sansone & Gerretsen 1960). Suppose that the Borel transform B 1 y ( z ) {\displaystyle {\mathcal {B}}_{1}y(z)} converges to an analytic function near 0 that can be analytically continued along the positive real axis to a function growing sufficiently ...
In mathematics, the Mittag-Leffler functions are a family of special functions. They are complex-valued functions of a complex argument z , and moreover depend on one or two complex parameters. The one-parameter Mittag-Leffler function , introduced by Gösta Mittag-Leffler in 1903, [ 1 ] [ 2 ] can be defined by the Maclaurin series
One way to work out those integrals is to obtain for them the corresponding recursion formulas as for the Mittag-Leffler polynomials using integration by parts. 1. For instance, [ 10 ] define for n ⩾ m ⩾ 2 {\displaystyle n\geqslant m\geqslant 2}
