About three in 10 restaurant operators — 29%— said they do not expect their business to return to normal levels for least a year, and another 32% said they believed it would be seven to 12 months ...

In this paper we show that binormal operators have nearest normal approximants. In fact, we exhibit nearest normals to such operators and, as a corollary, show that the hermitian part of a binormal ...

It has been proved recently [1] that a contraction, satisfying some complementary assumptions, is similar to a normal operator if and only if its resolvent grows at most linearly towards the spectrum.

AUSTIN, Texas (AP) — Texas’ grid operators say the electrical system has returned to normal for the first time since a winter storm knocked out power to more than 4 million customers. Smaller outages ...

Fuzzy normed linear spaces extend conventional normed spaces by integrating a degree of imprecision through fuzzy set theory, thereby quantifying uncertainty in the measurement of vector magnitude. In ...

How can you can tell it’s a bank holiday weekend? Because the bus companies are taking out ads boasting that they are quicker than the train. “We’re faster and hassle free to London,” is the promise ...
