A new kind of multivariate Hermite interpolation is proposed. The existence of the multivariate Hermite interpolation leads towards the construction of an extended Filon-type methods. Such methods attain good accuracy for all values of the oscillatory parameter when increasing, as required, the interpolation order. Numerical experiments are provided to illustrate the effectiveness of our approach.<\/p>","DOI":"10.1090\/mcom\/3797","type":"journal-article","created":{"date-parts":[[2022,10,13]],"date-time":"2022-10-13T08:22:14Z","timestamp":1665649334000},"page":"867-893","source":"Crossref","is-referenced-by-count":4,"title":["On an extended Filon method for highly oscillatory integrals over a simplex"],"prefix":"10.1090","volume":"92","author":[{"given":"Jing","family":"Gao","sequence":"first","affiliation":[]},{"given":"Arieh","family":"Iserles","sequence":"additional","affiliation":[]}],"member":"14","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"issue":"5","key":"1","doi-asserted-by":"publisher","first-page":"1984","DOI":"10.1137\/090779024","article-title":"Computing multivariate Fekete and Leja points by numerical linear algebra","volume":"48","author":"Bos, L.","year":"2010","journal-title":"SIAM J.
