  Landau notation - Wikipedia, the free encyclopedia
In complexity theory, computer science, and mathematics, Landau notation, also called "little o"- and "big O notation", is a mathematical notation used for asymptotic comparison of functions.
The advantage of the above notation is that it allows for the abuse of notation consisting in writing f = g + o(h) instead of f - g = o(h), which is quite handy in calculations of approximations obtained by (repeated) use of Taylor's theorem and formulae for this notation (see below).
Main applications of Landau notations are found in complexity theory and asymptotic analysis.

 Oregon Judicial Department Appellate Court Opinions
LANDAU, P. Claimant seeks judicial review of an order of the Workers' Compensation Board (board) upholding employer's denial of his claim on the ground that he failed to notify employer of his on-the-job injury within the time required by the statute.
The board concluded that the notation in the log supplied the required information as to when the injury occurred and at least arguably informed employer where the injury occurred.
While claimant's notations in the logbook are similar to those of other workers and appeared to satisfy the employer's reporting procedures, claimant's written reports of injury did not satisfy the precise requirements of ORS 656.265(2) that written notice apprise the employer of when and where and how the injury occurred."

Both of these symbols are introduced in a section entitled "Landau notation." This is slightly misleading, for while the "O" notation is traditionally attributed to Landau, the "<<" is usually attributed to Vinogradov.
The distribution of primes is a central subject in analytic number theory, and this topic is introduced in Chapter 5 with a heuristic discussion of the prime number theorem.
For example, when the "O" notation is first used, Stopple is very careful to indicate all of the details of the relevant inequalities.

                      LANDAU, P. Defendants Thomas A. McDonald and Marion F. McDonald moved to set aside a judgment, arguing that it was not renewed in a timely manner and that it therefore was void.
However, before the expiration of 10 years the circuit * * * court for the county in which the judgment originally was entered, on motion, may renew the judgment and cause a notation in the register and the judgment docket indicating the renewal of the judgment to be made.
By its terms, the statute required the court also to "cause a notation in the register and the judgment docket" before the expiration of that period.

 1965 Ford Thunderbird Special Landau
The Thunderbird Special Landau was introduced in the Spring of 1965, and differed from the regular Landau due to its unique combination of interior and exterior colors, as well as differences in trim.
The interior simulated woodgrain trim was of "burled walnut," a different pattern not used on the standard Landau models, and Special Landau nameplates mounted on the front door trim panels reminded occupants they were in something special.
The ROT sheet, which was used by the factory to assemble the car is sometimes found in the springs of the rear seat back on the left side of the car (driver's side).

 Simulation of Energy Loss Straggling
Landau theory assumes that the number of these collisions is high, and consequently, it has a restriction
First, the Landau theory and its limitations are discussed, and then, the Vavilov and Gaussian straggling functions and the methods in the thin layers and gaseous materials are presented.
A solution to this has been to introduce a limit on the value of the variable sampled by the Landau distribution in order to keep the average fluctuation to 0.

The state concedes that this court previously has determined that the imposition of upward departure sentences based on facts, other than the fact of a prior conviction, not admitted or found by a jury is plain error.

 Comments on the identification of high-order spectral lines of donors in semiconductors in intermediate magnetic fields
The magneto-optical spectrum of the shallow donors in n-GaAs is studied using a far-infrared laser at photon energies greater than the binding energy of the donors.
The transitions from the (1s) ground state into the Landau levels are not observed but, instead, series of transitions from the ground state into donor states associated with the individual Landau levels.
The strongest series corresponds to the (000)-(0N0) transitions and the second strongest series to (000-0N2) transitions where N is the index of the Landau level involved (and where the high-field notation is employed).

This complexity is studied asymptotically as a function of the size of entry datas; a sample is welcime : sorting a list of N elements could take a time such as k*N*Log(N), where k is a constant value.
The complexity is then said to be as O(N*Log(N)) (It's the asymptotic notation of Landau).
For the TSP, the entry data size is the number of cities and a measure of complexity if the number of permutations to test in order to obtain a solution.
