Classical harmonic research is a crucial a part of sleek physics and arithmetic, similar in its value with calculus. Created within the 18th and nineteenth centuries as a unique mathematical self-discipline it endured to strengthen (and nonetheless does), conquering new unforeseen parts and generating outstanding functions to a mess of difficulties, previous and new, starting from mathematics to optics, from geometry to quantum mechanics, let alone research and differential equations. the ability of team theoretic ideology is effectively illustrated through this wide selection of issues. it's broadly understood now that the reason of this striking strength stems from crew theoretic principles underlying essentially every thing in harmonic research. This quantity is an strange blend of the overall and summary crew theoretic procedure with a wealth of very concrete subject matters beautiful to everyone drawn to arithmetic. Mathematical literature on harmonic research abounds in books of roughly summary or concrete type, however the fortunate blend as within the current quantity can infrequently be present in any monograph. This publication may be very necessary to a large circle of readers, together with mathematicians, theoretical physicists and engineers.

Proof We prove the theorem in several steps. 1. The Steklov convolution fh«() = 11(+h h ( f(u) du, h > 0, (4) is also an entire function of finite degree, but it is bounded on 1Ft Indeed, on the real axis fh(~) = *(Xh * f)(~), where Xh is the characteristic function of the interval (0, h) c R.

To conclude the proof of (3) it remains to let h go to zero and to use the Lebesgue Convergence Theorem. Remark. Usually (cf. 2.
