ansatz

• “It would be useful to do a course on FEM because that way, the idea of using "ansatz" seems to begin to become more "natural.”

• “Get comfortable with the idea that the "ansatz" or the assumed form for the solution/potential form is purely arbitrary, even though no self-respecting author of mechanics/analytical mathematics would ever highlight this particular part about the analytical theory.”

• “Again, however, Stenger's paper demonstrates an ignorance of the relevant literature in the philosophy of physics, some of which is somewhat less enthusiastic about the Hartle-Hawking ansatz ...”

• “An ansatz to the ‘Talk Like a Physicist’ problem: Throw in random German words, like ‘brehmsstahlung’ and ‘zitterbewegung’.”

• “And what about the “homogeneous distribution” ansatz of FRW?”

• “PS – according to Mathworld, “An ansatz is an assumed form for a mathematical statement that is not based on any underlying theory or principle.””

• “The logarithm rule is an empirical rule of thumb ansatz? which describes the net result in ranges of interest, considering various isotopes, far bands, hot bands etc. , with the combination of changing linear and saturation effects being approximated by a logarithm.”

• “It is of course possible for a solution to concentrate its mass and energy in a different configuration than a bump function; but experience has shown that the most nonlinear behaviour tends to occur when such a concentration occurs, and so this ansatz is expected to capture the "worst-case" behaviour of the solution.”

  What's new

• “(One can also refine the above ansatz in a number of ways, for instance by also introducing a frequency modulation, which is particularly important in models such as the mass-critical NLS which admit a frequency modulation symmetry, but for simplicity we will not consider this more complicated situation here.)”

  What's new

• “These considerations illustrate how the commonly used semigroup ansatz for time evolution of the unstable systems arises.”
