  2. Lattice model (finance) - Wikipedia

    en.wikipedia.org/wiki/Lattice_model_(finance)

    at option maturity, value is based on moneyness for all nodes in that time-step; at earlier nodes, value is a function of the expected value of the option at the nodes in the later time step, discounted at the short-rate of the current node; where non-European value is the greater of this and the exercise value given the corresponding bond value.

  3. Matrix pencil - Wikipedia

    en.wikipedia.org/wiki/Matrix_pencil

    Matrix pencils play an important role in numerical linear algebra.The problem of finding the eigenvalues of a pencil is called the generalized eigenvalue problem.The most popular algorithm for this task is the QZ algorithm, which is an implicit version of the QR algorithm to solve the eigenvalue problem = without inverting the matrix (which is impossible when is singular, or numerically ...

  4. Current–voltage characteristic - Wikipedia

    en.wikipedia.org/wiki/Current–voltage...

    The simplest I–V curve is that of a resistor, which according to Ohm's law exhibits a linear relationship between the applied voltage and the resulting electric current; the current is proportional to the voltage, so the I–V curve is a straight line through the origin with positive slope.

  5. Present value - Wikipedia

    en.wikipedia.org/wiki/Present_value

    (In fact, the present value of a cashflow at a constant interest rate is mathematically one point in the Laplace transform of that cashflow, evaluated with the transform variable (usually denoted "s") equal to the interest rate. The full Laplace transform is the curve of all present values, plotted as a function of interest rate.

  6. Percolation theory - Wikipedia

    en.wikipedia.org/wiki/Percolation_theory

    For most infinite lattice graphs, p c cannot be calculated exactly, though in some cases p c there is an exact value. For example: For example: for the square lattice ℤ 2 in two dimensions, p c = ⁠ 1 / 2 ⁠ for bond percolation, a fact which was an open question for more than 20 years and was finally resolved by Harry Kesten in the early ...

  7. Actuarial present value - Wikipedia

    en.wikipedia.org/wiki/Actuarial_present_value

    The actuarial present value (APV) is the expected value of the present value of a contingent cash flow stream (i.e. a series of payments which may or may not be made). Actuarial present values are typically calculated for the benefit-payment or series of payments associated with life insurance and life annuities. The probability of a future ...

  8. Net present value - Wikipedia

    en.wikipedia.org/wiki/Net_present_value

    It compares the present value of money today to the present value of money in the future, taking inflation and returns into account. The NPV of a sequence of cash flows takes as input the cash flows and a discount rate or discount curve and outputs a present value, which is the current fair price .

  9. Power-voltage curve - Wikipedia

    en.wikipedia.org/wiki/Power-voltage_curve

    Power-voltage curve (also P-V curve) describes the relationship between the active power delivered to the electrical load and the voltage at the load terminals in an electric power system under a constant power factor. [1] When plotted with power as a horizontal axis, the curve resembles a human nose, thus it is sometimes called a nose curve. [2]
