Trace Class Operators

Famous quotes containing the words trace and/or class:

    Yet ere I can say where—the chariot hath
    Passed over them—nor other trace I find
    But as of foam after the ocean’s wrath
    Percy Bysshe Shelley (1792–1822)

    Where justice is denied, where poverty is enforced, where ignorance prevails, and where any one class is made to feel that society is in an organized conspiracy to oppress, rob, and degrade them, neither persons nor property will be safe.
    Frederick Douglass (c.1817–1895)
