In topology, the Tietze extension theorem states that continuous functions on a closed subset of a normal topological space can be extended to the entire space, preserving boundedness if necessary.
In the mathematical field of graph theory, Tietze's graph is an undirected cubic graph with 12 vertices and 18 edges. It is named after Heinrich Franz Friedrich Tietze, who showed in 1910 that the Möbius strip can be subdivided into six regions that all touch each other – three along the boundary of the strip and three along its center line – and therefore that graphs that are embedded onto the Möbius strip may require six colors. The boundary segments of the regions of Tietze's subdivision form an embedding of Tietze's graph.

Tietze syndrome is a benign inflammation of one or more of the costal cartilages. It was first described in 1921 by the German surgeon Alexander Tietze (1864–1927).
Nata de coco is a chewy, translucent, jelly-like food produced by the fermentation of coconut water, which gels through the production of microbial cellulose by Komagataeibacter xylinus. Originating in the Philippines, nata de coco is most commonly sweetened as a candy or dessert, and can accompany a variety of foods, including pickles, drinks, ice cream, puddings, and fruit cocktails.
Heinrich Franz Friedrich Tietze was an Austrian mathematician, famous for the Tietze extension theorem on functions from topological spaces to the real numbers. He also developed the Tietze transformations for group presentations, and was the first to pose the group isomorphism problem. Tietze's graph is also named after him; it describes the boundaries of a subdivision of the Möbius strip into six mutually-adjacent regions, found by Tietze as part of an extension of the four color theorem to non-orientable surfaces.
Costochondritis, also known as chest wall pain, costosternal syndrome, or costosternal chondrodynia is an acute and often temporary inflammation of the costal cartilage, the structure that connects each rib to the sternum at the costosternal joint. The condition is a common cause of chest pain. Though costochondritis often resolves on its own, it can be a recurring condition that has little or no signs of onset.
In group theory, Tietze transformations are used to transform a given presentation of a group into another, often simpler presentation of the same group. These transformations are named after Heinrich Franz Friedrich Tietze who introduced them in a paper in 1908.
Alexander Tietze was a German surgeon born in Liebenau. Tietze's syndrome is named after him.
The Liao dynasty was an empire established by the Khitans. This article discusses the provincial system that existed within the Liao dynasty from the early 10th century until the fall of the empire in 1125, in what is now North China, Northeast China and Mongolia.
Martin Tietze was a German luger who competed during the 1930s. He won seven medals at the European luge championships with five golds and two silvers. Tietze's four championships in the men's singles has not been equaled as of 2007.
Friedel Tietze (1908–1953) was a German luger who competed in the late 1930s. She won two gold medals in the women's singles event at the European luge championships.
The Hume's treecreeper, was earlier included within the brown-throated treecreeper complex and identified as a separate species on the basis of their distinctive calls. This species in the treecreeper family is found in Assam, Myanmar, Shan Mountains, Laos and the Dalat Plateau.
The Liao dynasty, also known as the Liao Empire, officially the Great Liao, or the Khitan (Qidan) State, was an empire in East Asia that ruled from 907 to 1125 over present-day Northern and Northeast China, Mongolia and portions of the Russian Far East and North Korea. The empire was founded by Yelü Abaoji, Khagan of the Khitans around the time of the collapse of Tang China and was the first state to control all of Manchuria.
Karin Tietze is a retired East German slalom canoeist who competed in the mid-1950s. She won two medals at the 1955 ICF Canoe Slalom World Championships in Tacen with a gold in the folding K-1 team event and a silver in the folding K-1 event.
Sybille Reinhardt is a German rower. At the East Germany rowing championships in July 1974, she was the youngest winner of one of the national titles at age 16; she won the double scull partnered with Christine Scheiblich. She has competed under her married name since 1980.
Christopher Tietze was a United States physician best known for his stance in the United States pro-choice movement to permit abortion in the United States.
Erica Tietze-Conrat (born June 20, 1883 Vienna, died December 12, 1958, in New York City, also known as Erika Conrat, Erica Tietze) was an Austrian-American art historian, one of the first women to study art history, a strong supporter of contemporary art in Vienna and an art historian specializing in Renaissance art and the Venetian school drawings.
Lakewood Heights is a residential neighborhood in Dallas, Texas (USA), bounded by Abrams Road to the east, Monticello Avenue to the north, Skillman Street to the west, and Richmond Avenue to the south. It is in the area known as East Dallas. Lakewood Heights is approximately one-half mile (0.8 km) wide (east-west) and three-quarters of a mile (1.2 km) long (north-south). It covers approximately 240 acres or slightly less than 0.375 square miles (1000m²). It is adjacent to several East Dallas neighborhoods, including Lakewood, Lower Greenville, and Wilshire Heights.
