    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

  3. Local trace formula - Wikipedia

    en.wikipedia.org/wiki/Local_trace_formula

    In mathematics, the local trace formula (Arthur 1991) is a local analogue of the Arthur–Selberg trace formula that describes the character of the representation of G(F) on the discrete part of L 2 (G(F)), for G a reductive algebraic group over a local field F.

  4. Arthur–Selberg trace formula - Wikipedia

    en.wikipedia.org/wiki/Arthur–Selberg_trace_formula

    In mathematics, the Arthur–Selberg trace formula is a generalization of the Selberg trace formula from the group SL 2 to arbitrary reductive groups over global fields, developed by James Arthur in a long series of papers from 1974 to 2003.

    An indoor location tracking map on a mobile phone. Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. . Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers of the network and the phone or by simply

  6. Petersson trace formula - Wikipedia

    en.wikipedia.org/wiki/Petersson_trace_formula

    In analytic number theory, the Petersson trace formula is a kind of orthogonality relation between coefficients of a holomorphic modular form. It is a specialization of the more general Kuznetsov trace formula. In its simplest form the Petersson trace formula is as follows.

    Trace formula may refer to: Arthur–Selberg trace formula , also known as invariant trace formula, Jacquet's relative trace formula, simple trace formula, stable trace formula Grothendieck trace formula , an analogue in algebraic geometry of the Lefschetz fixed-point theorem in algebraic topology , used to express the Hasse–Weil zeta function .

  8. Kuznetsov trace formula - Wikipedia

    en.wikipedia.org/wiki/Kuznetsov_trace_formula

    While the usual trace formula studies the harmonic analysis on G, the relative trace formula is a tool for studying the harmonic analysis on the symmetric space /. For an overview and numerous applications Cogdell, J.W. and I. Piatetski-Shapiro, The arithmetic and spectral analysis of Poincaré series , volume 13 of Perspectives in mathematics .

  9. Trace class - Wikipedia

    en.wikipedia.org/wiki/Trace_class

    In mathematics, specifically functional analysis, a trace-class operator is a linear operator for which a trace may be defined, such that the trace is a finite number independent of the choice of basis used to compute the trace. This trace of trace-class operators generalizes the trace of matrices studied in linear algebra.
