Mathematik für Wirtschaftswissenschaftler


Mathematik für Wirtschaftswissenschaftler: Eine präzise und anwendungsorientierte Einführung
Deutsch | 2026 | ISBN: 3658505206 | 837 Pages | PDF (True) | 53 MB
Nicht nur in den Wirtschaftswissenschaften wird die Bedeutung der Mathematik immer größer. In Zeiten von Big Data, Business Analytics und Reinforcement Learning können qualitativ gute, informierte Entscheidungen nur getroffen werden, wenn man die Sprache der Mathematik versteht, Annahmen hinterfragen kann und Grundprinzipien verstanden wurden. Dieses Buch dient als Einführung in dieses Themengebiet für Wirtschaftswissenschaftler im ersten Studienjahr des Bachelors. Es deckt dabei Grundlagen wie Mengentheorie und Eigenschaften von Funktionen ebenso ab wie fortgeschrittenere Themen der linearen Algebra oder Optimierung. Beispiele aus der Volkswirtschaftslehre oder dem Finance illustrieren dabei vereinzelt die Anwendung in späteren Vorlesungen.

Mathematics as the Science of Patterns


Mathematics as the Science of Patterns: Making the Invisible Visible to Students Through Teaching
English | 2022 | ISBN: 1648027458 | 266 Pages | PDF (True) | 7 MB
Mathematics as the Science of Patterns: Making the Invisible Visible to Students through Teaching introduces the reader to a collection of thoughtful, research-based works by authors that represent current thinking about mathematics, mathematics education, and the preparation of mathematics teachers. Each chapter focuses on mathematics teaching and the preparation of teachers who will enter classrooms to instruct the next generation of students in mathematics. The value of patterns to the teaching and learning of mathematics is well understood, both in terms of research and application. When we involve or appeal to pattern in teaching mathematics, it is usually because we are trying to help students to extract greater meaning, or enjoyment, or both, from the experience of learning environments within which they are occupied, and perhaps also to facilitate remembering. As a general skill it is thought that the ability to discern a pattern is a precursor to the ability to generalize and abstract, a skill essential in the early years of learning and beyond. Research indicates that the larger problem in teaching mathematics does not lie primarily with students; rather it is with the teachers themselves.

Mathematical Demography Theory and Modeling


Mathematical Demography: Theory and Modeling
English | 2026 | ISBN: 9819561280 | 175 Pages | PDF EPUB (True) | 14 MB
This textbook is written with the intention of providing the essentials of foundational training in modeling, both mathematical and stochastic. It offers a comprehensive understanding of theoretical and formal mathematical demography and human population dynamics. Presented in an engaging, clear and concise manner, it aims to outline traditional material and recent advancements in the field, specifically tailored for both beginners and professionals. Separate chapters discuss classical as well as recent developments in stable and stationary populations, such as Euler-Lotka population equations, and life tables. Partial differential equations models of single population dynamics, McKendrick von Foerster models of population growth and Okubo's diffusion models are derived. Population ecology models like the Lotka-Volterra two-population framework, Kermack-McKendrick three-population models, and their stability analysis foundations are succinctly explained. Recent advancements in stationary population theories and newer population stability principles developed are included. The book also includes two chapters on stochastic process models in demography. The content of the book is not only accessible and relevant to students and researchers in mathematical demography but also to those working in actuarial science, ecology, statistics and mathematical modeling.
