Human-Centric Aspects of Software Architecture

Prof. Rick Kazman & Prof. Hong-Mei Chen
University of Hawaii, Honolulu


In 1992 the political consultant James Carville coined the much-quoted phrase “It’s the economy, stupid”. I shamelessly borrow and adapt Carville’s line, in the context of software architecture to be: “It’s the people, stupid”. A software architecture is not merely a technical artifact; it is a socio-technical artifact. Architects who forget or neglect this critical aspect of their architecture are doomed to failure. An architect is the fulcrum between the world of technology on the one hand, and the world of individuals, groups, and business needs on the other hand. An architect therefore needs to be not just a technical leader, but also a community shepherd. In this talk I will outline some of the non-technical dimensions of a software architect’s job, and describe some of the ways in which these can cause a project to succeed or fail. In addition I will show how a socio-technical ecosystem – a network representation of the technical artifacts as well as the human artifacts – can be captured, modeled, and analyzed, and the ways in which a project can be made better through this analytic lens.

Geometric Analysis

Prof. Antonio Greco
Dipartimento di Matematica e Informatica
Università degli Studi di Cagliari


The course is an introduction to the problem of determining the shape of solutions to boundary-value problems for second-order partial differential equations, mainly of elliptic type, occasionally parabolic.


– Review of the weak maximum principle, the strong maximum principle, and the Hopf lemma.
– Some motivations for Geometric Analysis and some characteristic results: the soap bubble theorem (Aleksandrov’s theorem), Serrin’s overdetermined problem, the Gidas-Ni-Nirenberg symmetry result.
– Convexity of solutions to the Dirichlet problem. Quasiconvexity.
– The Morse index of a solution and its role in Geometric Analysis. Work in progress.


The course spans over 8 lectures of 2 hours each (16 hours total), one lecture per week. Details will be specified on the occasion of the first lecture, which will be given on October 20, 2023 at 4 p.m. in room B of the Department of Mathematics and Computer Science


The final exam consists in a presentation, and it can be recognized as 3.2 CFR.
