Many interesting applications in mathematics and physics have been known, including the description of WZW terms, string structures, the study of conformal immersions, and classifications of Ramond\u2013Ramond fields, to list a few. Additionally, it is an interesting application of the theory of infinity categories. In this paper, we give an expository account of differential cohomology and the classification of higher line bundles (also known as S1-banded gerbes) with a connection.We begin with how \u010cech cohomology is used to classify principal bundles and define their characteristic classes, introduce differential cohomology \u00e0 la Cheeger and Simons, and introduce S1-banded gerbes with a connection.<\/jats:p>","DOI":"10.3390\/axioms13010060","type":"journal-article","created":{"date-parts":[[2024,1,19]],"date-time":"2024-01-19T03:33:41Z","timestamp":1705635221000},"page":"60","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Differential Cohomology and Gerbes: An Introduction to Higher Differential Geometry"],"prefix":"10.3390","volume":"13","author":[{"given":"Byungdo","family":"Park","sequence":"first","affiliation":[{"name":"Department of Mathematics Education, Chungbuk National University, Cheongju 28644, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"149","DOI":"10.4310\/ATMP.2012.v16.n1.a5","article-title":"\u010cech cocycles for differential characteristic classes: An \u221e-Lie theoretic construction","volume":"16","author":"Fiorenza","year":"2012","journal-title":"Adv.
