A sequence whose elements become arbitrarily close to each other is known as his namesake type of sequence.
A principle sometimes named for this mathematician deals with the difference between the number of zeros and the number of poles of a meromorphic function, and is used to derive the Nyquist stability criterion. He names a theorem generalized by Sylow's first theorem which states that, given a finite group G and a prime p, G has an element of order p if p divides the order of G. His namesake type of (*) surface is one which is intersected by a causal curve exactly once. He co-names the integral test for convergence with Maclaurin. A sequence whose elements become arbitrarily close to each other is known as his namesake type of sequence. He is the first namesake of a relation which states that absolute value of the inner product of two vectors is less than or equal to the product of their norms. For 10 points, name this mathematician who names an inequality with Schwarz.
