Elementary Numerical Mathematics for Programmers and Engineers
暫譯: 程式設計師與工程師的基礎數值數學

Gisbert Stoyan worked for more than 10 years on industrial problems at the WIAS in Berlin and taught numerical mathematics at ELTE University (Budapest, Hungary) for over 30 years. His research publications were mostly on the numerical solution of partial differential equations. His three-volume textbook Numerical Methods I-III, published in Hungarian, brings together his experiences in areas including (along with the basic topics like numerical linear algebra and nonlinear equations) strongly stable methods for ODEs, multigrid algorithms, finite element praxis and theory, finite elements for Navier-Stokes equations, and methods for first-order hyperbolic equations.

Gisbert Stoyan passed away in 2018.

Agnes Baran received her PhD in Mathematics in 2008 at the University of Debrecen under the supervision of Gisbert Stoyan. Her doctoral thesis was on high-order finite element methods for Stokes equations. She works as an associate professor at the Faculty of Informatics at the University of Debrecen where she teaches courses on Numerical Methods and Optimization for students of Mathematics and Computer Science.

吉斯伯特·斯托揚（Gisbert Stoyan） 在柏林的 WIAS 從事工業問題研究超過 10 年，並在 ELTE 大學（匈牙利布達佩斯）教授數值數學超過 30 年。他的研究出版物主要集中在偏微分方程的數值解法上。他的三卷本教科書《數值方法 I-III》（Numerical Methods I-III）以匈牙利文出版，匯集了他在包括數值線性代數和非線性方程等基本主題之外的經驗，涵蓋了常微分方程的強穩定方法、多重網格算法、有限元素實務與理論、納維-斯托克斯方程的有限元素以及一階雙曲方程的方法。

吉斯伯特·斯托揚於 2018 年去世。

阿格尼絲·巴蘭（Agnes Baran） 於 2008 年在德布勒森大學獲得數學博士學位，指導教授為吉斯伯特·斯托揚。她的博士論文研究的是斯托克斯方程的高階有限元素方法。她目前擔任德布勒森大學資訊學院的副教授，教授數值方法和優化課程，面向數學和計算機科學的學生。
