"The tenth edition of this bestselling text includes examples in more detail and more applied exercises; both changes are aimed at making the material more relevant and accessible to readers. Kreyszig introduces engineers and computer scientists to advanced math topics as they relate to practical problems."

"Zeta-function regularization is a powerful method in perturbation theory, and this book is a comprehensive guide for the student of this subject. Everything is explained in detail, in particular the mathematical difficulties and tricky points, and several applications are given to show how the procedure works in practice, for example in the Casimir effect, gravity and string theory, high-temperature phase transition, topological symmetry breaking, and non-commutative spacetime. The formulae, some of which are new, can be directly applied in creating physically meaningful, accurate numerical calculations. The book acts both as a basic introduction and a collection of exercises for those who want to apply this regularization procedure in practice. "

"This book presents the various types of coherent states introduced and studied in the physics and mathematics literature and describes their properties together with application to quantum physics problems. It is intended to serve as a compendium on coherent states and their applications for physicists and mathematicians, stretching from the basic mathematical structures of generalized coherent states in the sense of Perelomov via the semiclassical evolution of coherent states to various specific examples of coherent states (hydrogen atom, quantum oscillator, ...)."

"Operator evolusi waktu merupakan pembawa dinamika dalam mekanika kuantum. Keadaan stasioner suatu partikel mengakibatkan bahwa fungsi gelombangnya dapat dipisahkan dengan separasi variabel. Secara analitik faktor dinamika seringkali dihilangkan karena keterbatasan kemampuan penghitungan. Dengan bantuan komputer posisi dan dinamika partikel dapat digambarkan secara utuh melaui penyelesaian persamaan schrodinger gayut waktu. Untuk itu perlu suatu skema numerik untuk operator evolusi waktu. Dalam paper ini akan diajukan skema numerik yang mungkin untuk memodelkan operator evolusi waktu diantaranya model Baker Champbel Hausdorf, dan model Richardson."

"Questo testo, che nasce dall'esperienza didattica degli autori, si propone di introdurre gli aspetti fondamentali della teoria della probabilità e dei processi stocastici, guardando con particolare attenzione alle connessioni con la meccanica statistica, il caos, le applicazioni modellistiche ed i metodi numerici. La prima parte è costituita da un'introduzione generale alla probabilità con particolare enfasi sulla probabilità condizionata, le densità marginali e i teoremi limite. Nella seconda parte, prendendo spunto dal moto Browniano, sono presentati i concetti fondamentali dei processi stocastici (catene di Markov, equazione di Fokker- Planck). La terza parte è una selezione di argomenti avanzati che possono essere trattati in corsi della laurea specialistica."
