Mr. Kasamoto said that he, Mr. Wright and Mr. Jandhyala had met Wednesday morning with the university’s events coordinator, and that they wanted “to make this a positive, collaborative experience.” In his Facebook message on Tuesday, he wrote, “We hope that ‘campus officials’ will contact us directly about any of their concerns regarding our efforts to make this event a success for the Berkeley community.”

Mr. Mogulof said Tuesday that the student organizers “know exactly” what the requirements are and that university officials had “repeatedly asked” them to provide specific documents.

Berkeley has been a hotbed of controversy this year, with a series of planned — and, in some cases, later canceled — speeches by conservatives whom opponents accused of promoting bigotry.

In February, Berkeley canceled a speech by Mr. Yiannopoulos — a former Breitbart News editor who has gleefully rejected “political correctness” and denigrated feminists, Muslims, transgender people and other groups — after initially peaceful protests on campus turned violent. Ms. Coulter, a conservative commentator known for many similar stances, was scheduled to speak in April, but the university canceled the event a week beforehand, saying it could not assure “the safety of Ms. Coulter, the event sponsors, audience and bystanders.” Both speakers had been invited by the Berkeley College Republicans.

Conservatives, including Mr. Yiannopoulos and Ms. Coulter, have accused the university of suppressing free speech. Many noted that Berkeley was the birthplace of the free speech movement and a cradle of liberal activism in the 1960s, and accused its students of having different standards for liberal and conservative speech. Opponents argued in response that the views Mr. Yiannopoulos and Ms. Coulter promoted against marginalized groups should be outside the bounds of civil discourse.

But when Mayor Jesse Arreguin of Berkeley asked the university last month to cancel Mr. Yiannopoulos’s Free Speech Week address, the university declined, saying it would not reject student groups’ invited speakers based on their political beliefs.
