calculus of residues afmârik-e mândehâ Fr.: calcul des résidus The application of → Cauchy's theorem to compute residues and poles, evaluate contour integrals, sum infinite series, and carry out related calculations. → calculus; residue from O.Fr. résidu, from L. residuum "a remainder," neut. of residuus "remaining, left over," from residere "remain behind." Afmârik, → calculus; mândehâ, plural of mândé "remained," from mândan "to remain," Mid.Pers. mânidan, mânenitan, O.Pers./Av. man- "to remain, to stay," Skt. mand-, mamandhi "to stand still, pause," Gk. menein "to wait." |
residue mândé (#) Fr.: résidu General:
Something that remains after a process involving the removal of part
of the original has been completed. M.E., from O.Fr. residu, from L. residuum "a remainder," neuter of residuus "remaining, left over," from residere "to remain behind." Mândé p.p. of mândan "to remain, stay" (mân "house, home;" Mid.Pers. mândan "to remain, stay;" O.Pers. mān- "to remain, dwell;" Av. man- "to remain, dwell; to wait;" Gk. menein "to remain;" L. manere "to stay, abide" (Fr. maison, ménage; E. manor, mansion, permanent); PIE base *men- "to remain, wait for"). |
residue theorem farbin-e mândehâ Fr.: théorème des résidus The theorem stating that the value of the line integral of a complex function, taken along a simple closed curve encircling a finite number of isolated singularities, is given by 2πi times the sum of the residues of the function at each of the singularities. |
