Complex Function Differentiability
The articles [17], [18], [3], [5], [4], [8], [2], [7], [11], [6], [16], [12], [19], [9], [10], [1], [14], [15], and [13] provide the notation and terminology for this paper. For simplicity, we use the following convention: k, n, m denote elements of N, X denotes a set, s1, s2 denote complex sequences, Y denotes a subset of C, f , f1, f2 denote partial functions from C to C, r denotes a real num...
متن کاملDIFFERENTIABILITY OF COMPLEX FUNCTIONS Contents
lim h→0 f(z + h)− f(z) h if this limit exists. If the derivative of f exists at z, we denote its value by f ′(z), and we say f isholomorphic at z. If f is holomorphic at every point of an open set U we say that f is holomorphic on U . This definition naturally leads to several basic remarks. First, the definition formally looks identical to the limit definition of a derivative of a function of ...
متن کاملDifferentiability of the arithmetic volume function
— We introduce the positive intersection product in Arakelov geometry and prove that the arithmetic volume function is continuously differentiable. As applications, we compute the distribution function of the asymptotic measure of a Hermitian line bundle and several other arithmetic invariants. Résumé. — On introduit le produit d’intersection positive en géométrie d’Arakelov et on démontre que ...
متن کاملModifications of Thomae's Function and Differentiability
As we shall see later, Thomae’s function is not differentiable on the irrationals. In this note, we address whether there is a modification of Thomae’s function which is differentiable on a subset of the irrationals. In Section 2, we prove that Thomae’s function is not differentiable on the irrationals and define modified versions of Thomae’s function. In Section 3, we show that for each of our...
متن کاملOn the Differentiability of the Policy Function∗
* The Research presented here started in August 1986 during our stay at the IMSSS, Stanford University; it was continued there during the Summer of 1987 and at the Insti-tuto de Analisis Economica, Universitat Autonoma de Barcelona in June-July 1988. We are very grateful to these institutions for their warm hospitality and support. Conversations with Manuel Santos and José Scheinkman were very ...
