Delta, английский
- A symbol used to indicate deviation or difference.
- Коэффициент “дельта” . показатель чувствительности рассчитываемой стоимости опциона к незначительным колебаниям цены базового актива. часто называется “хеджевым коэффициентом” (hedge ratio). изменяется в интервале от 0 до 1 для опционов колл и в интервале
- The fourth letter of the greek alphabet
- Дельта (тип якоря)
- A name given by the greeks to the alluvial tract inclosed between the bifurcating branches of the nile and the sea-line. it is well known that rivers which deposit great quantities of matter, do also very often separate into two or more branches, previous to their discharge into the sea; thus forming triangular spaces, aptly called deltas from their resemblance to the greek letter {d}.
- [1] alluvial deposit at the mouth of a river or tidal inlet. [2] nato phonetic notation for letter “d” which, when used as a single-letter signal, signifies “stand clear—i am maneuvering with difficulty” (see table 8). [3] a triangular-shaped aerofoil. 95 delta demi-culverin: a 16th century cannon firing a 9-pound ball.
- Допустимая ошибка
- A body of alluvium, nearly flat and fan-shaped, deposited at or near the mouth of a river or stream where it enters a body of relatively quiet water, usually a sea or lake. hp
- The ratio of the change in price of an option to the change in price of the underlying asset. also called the hedge ratio. applies to derivative products. for a call option on a stock, a delta of 0.50 means that for every $1.00 that the stock goes up, the option price rises by $0.50. as options near expiration, in-the-money call option contracts approach a delta of 1.0, while in-the-money put options approach a delta of -1. see: hedge ratio, neutral hedge. call deltas range from 0.00 to +1.00; put deltas range from 0.00 to -1.00. if the call delta is 0.69, the put delta is -0.31 (call delta minus 1 equals put delta; 0.69 -1 =-0.31).

- When a non-linear dynamic system develops twice the possible solutions that it had before it passed its critical level. a bifurcation cascade is often called the period doubling route to chaos because the transition from an orderly system to a chaotic system often occurs when the number of possible solutions begins increasing, doubling each time.

Dendritic drainage pattern, английский
A common drainage pattern in which the tributaries join the gently curving mainstream at acute angles, resembling in plan view the branching habit of an oak or chestnut tree; it is produced where a consequent stream receives several tributaries which in turn are fed by smaller tributaries. it indicates streams flowing across horizontal rock strata and homogenous soil typified by the landforms of soft sedimentary rocks, volcanic tuff, old dissected coastal plains, or complex crystalline rocks offering uniform resistance to erosion. sw, wa, gg
Degradation [geomorphology], английский
