Marc Voorhoeve
Marc Voorhoeve (5 April 1950, Amsterdam – 7 October 2011, Eindhoven) was a Dutch mathematician who introduced the Voorhoeve index of a complex function in 1976. Marc studied at the University of Leiden where he wrote a thesis on exponential polynomials. The Voorhoeve index is a result from this work. He then worked at Centrum Wiskunde & Informatica and at ''Philips Data Systems'', a division of Philips that manufactured minicomputers. From 1985 to 2011, he was assistant professor in Kees van Hee's group at Eindhoven University of Technology, which specialized in business process modeling techniques based on sound mathematical principles, in particular Petri nets and process algebra., link from University of Augsburg Publications * See also * Petersen's theorem In the mathematical discipline of graph theory, Petersen's theorem, named after Julius Petersen, is one of the earliest results in graph theory and can be stated as follows: Petersen's Theorem.

Voorhoeve Index
In mathematics, the Voorhoeve index is a non-negative real number associated with certain Function (mathematics), functions on the complex numbers, named after Marc Voorhoeve. It may be used to extend Rolle's theorem from real functions to complex functions, taking the role that for real functions is played by the number of zeros of the function in an interval (mathematics), interval. Definition The Voorhoeve index V_I(f) of a complex-valued function ''f'' that is analytic function, analytic in a complex Neighbourhood (mathematics), neighbourhood of the real interval I = [''a'', ''b''] is given by : V_I(f) = \frac\int_a^b \! \left, \frac \, f(t) \ \,\, dt \, = \frac \int_a^b \! \left, \left(\frac\right) \ \, dt. (Different authors use different normalization factors.) Rolle's theorem Rolle's theorem states that if f is a continuously differentiable function, continuously differentiable real-valued function on the real line, and f(a)= f(b)=0, where a [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
